плавах реалізується більш високий ступінь впо-
рядкованості атомів міді у порівнянні з чистою
міддю, що приводить і до більш впорядкованого
розподілу атомів алюмінію з найближчого ото-
чення атомів міді.
РЕЗЮМЕ. Проведено рентгенодифракционное иссле-
дование структуры расплавов системы Al—Cu с содер-
жанием 0, 14, 25, 30, 40 и 100 % ат. Cu при температурах
вблизи линии ликвидуса. Методом обратного Монте–
Карло, с использованием экспериментальных кривых стру-
ктурного фактора (СФ), реконструированы структурные
модели, согласно которымх рассчитаны парциальные ха-
рактеристики локального упорядочения атомов в рас-
плавах. Установлено, что существование предпика на
кривых СФ есть следствие корреляции в положении ато-
мов меди на расстояниях 4.7 Ao , которые преимуществен-
но реализуются в политетраэдрических кластерах ико-
саэдрического типа, существенно обогащенных, в сравне-
нии с составом расплава, атомами меди. Характер упоря-
дочения атомов в кластерах определяет структуру и сво-
йства расплавов Al—Cu. Заметное сокращение межато-
мных расстояний коррелирует с характером концентра-
ционной зависимости термодинамических свойств расп-
лавов, которые указывают на существенные отрицатель-
ные отклонения от идеальности.
SUMMARY. Structure of Al–Cu liquid alloys with
0,14,25,30,40 % at. Cu has been studied by X-ray diffraction
at temperatures near liquidus. The structural models of
liquid alloys have been reconstructed by means of Reverse
Monte-Carlo method with use of experimental curves of
the structural factor (SF). The partial characteristics of lo-
cal ordering of atoms in alloys were calculated from the-
se models. It have been established, that the prepeak on
the experimantal SF curves is caused by a correlation in
arrangement of copper at a distances of about 4.7 Ao
atoms in polytetrahedral clusters of icosahedral type. These
clusters more enriched atoms of copper in comparison with
melt composition. Character of atomic ordering in clusters
defines structure and properties of liquid Al—Cu alloys.
The significant decreasing of interatomic distances corre-
lates with concentration dependence of thermodynamic
properties of melts that points on deviations from ideality.

organic luminophors has been shown. Basing on quantum-chemical calculations of luminophore average molecular
radii, consideration of their dissociated ion charges as well as on experimental results of the molecules entering
into crystals, the coherent criterion of the built-in molecule conjuga-tion (CCC) with the lattice points has been
proposed. That approach can be proposed for modifying various water-soluble crystals with organic luminophores.
It is known that crystals of inorganic compo-
unds grown from aqueous solutions can be doped in
the course of growing with molecules of organic sub-
stances being dissolved in the mother solution [1]. Tho-
se crystals modified with organic compounds gain
new physical and chemical properties and can be
applied in various fields of science and engineering.
Doping of KDP crystals with organic luminophores
allow to develop the scintillation detectors of ioni-
zing radiation or solid elements for dye lasers. In this
work, the experimental results are presented on KDP
crystals doped with luminophores on the base of
naphthalic and perylene tetracarboxylic acid derivati-
ves, phtalocyanines, and some naphthalene deri-
vatives as well as generalized literature data on buil-
ding-in of various organic substances into KDP crystal
lattice [2—4].
The KDP single crystals were grown by decreasing
temperature from 50 to 40 оC. The solution supersa-
turation during the growing was provided to be at
least 5 %. Organic luminophores were introduced as
aqueous solutions of luminophores with KDP into
mother liquid at the crystal growing temperature. The
concentration of doping luminophore was varied from
10–1 to 10–4 wt %. Nо influence of luminophore ad-
mixtures on the solution acidity (pH) or saturation tem-
perature was observed. Stoichiometric solutions with
pH 4.0—4.1 were used. The luminophores fluorescing
in KDP solution under UV radiation were chosen for
the study. Emission spectra of solutions and crystals
were measured using Cary Eclips and Hitachi F4010
spectrofluorimeters. The building-in of luminophores
into the KDP lattice was judged from the crystal flu-
orescence. The structures of organic luminophores used
in our experiments as well as of compounds used by
other authors to dope KDP crystals are shown in
table 1. In all cases, the building-in of dye molecules
into KDP crystal lattice was proven by the absorption
or fluorescence electron spectroscopy [2—4]. The quan-
tum-chemical optimization of molecular geometry was
provided using the AMI method (MOPAC 2000 sof-
tware [8, 9]). The average molecule radius was deter-
mined as the geometrical mean of ellipse axes using the
formula R=1/2
3
√abc , where a is the segment [a] length
between the most distant of the molecule atoms (mole-
cular "length"); b, the segment [b] length between the
most distant atoms in any direction perpendicular to
segment [a] (molecular "width"); c, the segment [c]
length between the most distant atoms in the direction
perpendicular to the plane defined by segments [a] and
[b] (molecular "height"). When calculating the segment
lengths, the Van der Waals atomic radii were taken
into account.
As is shown in [3, 5], the organic dye admixtures
enter selectively in various segments of a growing
KDP crystal. Such micro-impurity distribution can be
explained by charge state of the growing crystal faces.
In [6], basing on experimental data on X-ray diffrac-
tion from KDP growing faces at small angles of inci-
dence, it is shown that K+ ions emerge on the face
[101], and alternate rows of K+ and H2PO4
– ions —
on the face [100]. As a result, the [101] face has a
total positive charge while [100] is neutral. In aqueous
solution, the organic luminophore molecules dissoci-
ate forming both negative and positive ions, which
tend to be adsorbed on opposite charged crystal faces.
The spatial structures of luminophore molecules dif-
fer too much from KDP unit cell; however, when
the difference between interatomic distances on the
crystal face surface and in the organic molecules is
negligible, the local stoichiometric conformity is pos-
sible, and the molecule can be captured by the grow-
ing face [7].
The water solutions of KDP and luminophores
1, 2, 6, 10, 11 investigated by us fluoresce in 350 to
600 nm range. On the contrary, the KDP single crystals
grown with luminophores 1, 2, 6 admixtures, show no
fluorescence as well as the crystals grown without fluo-
rescent substances additives (with a micro-impurity
content at most 1⋅10–4 wt %). Thus, we have concluded,
that 1, 2, 6 do not enter the KDP lattice. The crys-
tals grown with luminophores 10 and 11 fluoresce
in 580 and 400 nm range, respectively.
The interatomic distance comparison between K+
ions in pyramid face [101] with geometrical molecular
parameters of 10 and 11 has shown that the distance
between negatively charged dissociated sulfonic acid
groups of luminophores differ from that between K+
ions in the direction [011] by less than 5 %. The lu-
minophores 1 and 2 molecules, which are not built-in,
are similar in size to those of 10 and 11, but differ
therefrom because contain only one sulfonic acid group.
Thus, it follows from the experimental results that
the negative ions of the dissociated luminophore mo-
lecules enter the KDP lattice in positively charged
pyramid growth segment only when the organic mole-
cule contains at least two SO3
2– functional groups in
its structure. The SO3
2– groups must be located in the

structure in such manner that the charge distributi-
on thereon conforms to periodic distribution of K+
charges in growing plane [101].
It is necessary to note that the planar molecule
of a luminophore may be located within limits of se-
veral crystal unit cells. In this case, the coherent conju-
gation of crystal lattice parameters with luminophore
molecular anion is provided. The luminophore may
be adsorbed by the growing plane and disposed wit-
hin the interplanar space during crystal face [101]
layer-by-layer growing.
Consideration of the results obtained as well as
literature data shows that molecules of cationic and
neutral dyes do not build-in into KDP crystal lat-
tices. As to anionic dyes, their building-in is observed
mainly for two-, three-, and four-charged anions.
Singly charged anionic dyes may behave in different
manners, depending on the particle size. So, large-
size single-charged anions do not build-in in KDP
crystal grate. At the same time, anions of small
average radius r, for example, cumarin derivatives
24 and 25 or alkylsulfates 30 and 31, may be absor-
bed in crystals.
Unfortunately, at present, there is no unified
criterion, which would define the capability of an
organic molecule entry into crystal lattice and pro-
vide a provisional selection of luminophores wit-
hout obligatory experimental examination of their
absorption in crystals. Obviously, this criterion
should take into account not only the anion charge
and size, but also opportunity of coherent conju-
gation between the crystal lattice parameters and
the arrangement of the charged groups in the lumi-
nophore molecule.
The probability of organic anion building-in into
a lattice depends on potential of an electric field cre-
ated by it, as well as on potential of the field in the
lattice layer, where building-in of an ion takes place.
Therefore, it is logical to assume that a criterion for
estimation of building-in capability should have the
same nature. Taking into account all the above, we
have proposed the coherent conjugation criterion
(CCC) equal to the dye ion charge/average radius ratio.
This criterion has dimention of potential of electric
field created by this ion:
CCC = –Z /r . (1)
Figure shows the dependence of CCC on the pa-
rameter r calculated by us using quantum-chemical
methods (table 1). Black circles mark organic ions,
which were included in lattice KDP, the cases when
introduction of anions in a lattice was not observed
are marked by open circles. As follows from these
data, the building-in of organic ions into KDP crys-
tals is observed if the CCC value exceeds 0.38 e/Ao .
The deviation from that value does not exceed 2.6 %
for all studied dyes. In our opinion, the cause of de-
viations (compounds 1, 13, 22 with CCC=0.38 to 0.39
do not build-in, while compound 24 with CCC=0.37
builds-in), consists in that the parameter r is estimated
roughly and electron density in organic anions is dist-
ributed inhomogeneously.
It is obvious that CCC parameter is also defined
by the crystal lattice type, ion charge and size of ions
forming it. That is why the value 0.38 is typical only
for KDP crystals and will be different at doping crys-
tals of other salts by organic anions.
The coherent conjugation criterion also can be used
for more detailed analysis of dye molecules building-
in capabilities into salt crystal lattices. Thus, for exam-
ple, proceeding from CCC value, we can define the li-
miting ion average radius (R lim), above which the ad-
sorption becomes impossible. R lim value comes to ~2.6
Ao for single charged ions, and 5.3, 7.9 Ao for two-
and three-charged ions, respectively.
In case of organic anions capable of step-by-step
dissociation, the CCC use allows to estimate the mi-
nimal charge necessary for the ion building-in into
KDP crystal lattice and then to calculate pH of solu-
tion at which absorption of the anion will take pla-
ce. Thus, for adenosine di-, three-, and tetraphospha-
te ions, the minimal charge must be at least — 2e
(table 2). Besides R lim value, limiting the built-in ion
size, the presence of another limiting parameter Rmax
can be supposed that is associated with the interlayer
distance in the KDP crystal lattice. If, in the multi-
charged ions case, R lim > Rmax, the dye ions will not

build-in into the lattice, despite of CCC > 0.38. How-
ever, at present, the analysis of disposable anionic
dyes does not allow to determine the Rmax value.
Finally, it should be noted that the suggested
parameter CCC is close in dimention to the Semen-
chenko parameter of the generalized moment. How-
ever, this parameter is used to describe ionic and me-
tal liquids as well as for thermodynamic calculations
of the surface phenomena involving ions at the liquid/
gas interface [10].
Thus, the adsorption of organic luminophore ani-
ons by KDP crystal growing faces is limited both
by the molecular spatial parameters and charge
distribution in the molecular dissociation products.
The coherent conjugation criterion (CCC) has been
proposed equal to organic anion charge/average ra-
dius ratio. It has dimention of electric potential created
by this ion. The CCC parameter is also defined by
crystal lattice type, charges and sizes of ions forming
it. Thus, CCC will be different for crystals of different
salts. For KDP crystals, this value is 0.38.

Voronov, V.B. Distanov, A.D. Roshal // Украинский химический журнал. — 2008. — Т. 74, № 1. — С. 36-41. — Бібліогр.: 10 назв. — англ. 0041–6045 https://nasplib.isofts.kiev.ua/handle/123456789/14472 548.5 Experimental study results on the conditions of KDP single crystal growing doped by organic luminophors have been presented. A possible coherent conjugation scheme for crystal-chemical parameters of KDP lattice with some organic luminophors has been shown. Basing on quantum-chemical calculations of luminophore average molecular radii, consideration of their dissociated ion charges as well as on experimental results of the molecules entering into crystals, the coherent criterion of the built-in molecule conjuga-tion (CCC) with the lattice points has been proposed. That approach can be proposed for modifying various water-soluble crystals with organic luminophores. Представлено результати експеримен- тальних досліджень умов вирощування монокристалів KДП, легованих органічними люмінофорами. Подано схему можливого когерентного спряження кристало-хімічних параметрів гратки KДП з деякими органічними люмінофорами. На підставі квантово-хімічних розрахунків середнього радіусу молекул люмінофорів, аналізу величин зарядів їx дисоційованих йонів, а також експериментальних результатів щодо входження молекул у кристали запропоновано критерій когерентного спряження (ККС) молекули, яка входить у вузли гратки. Даний підхід може бути запропонований для модифікування органічними люмінофорами різних водорозчинних кристалів. Представлены результаты экспериментальных исследований условий выращивания монокристаллов KДП, легированных органическими люминофорами. Показана схема возможного когерентного сопряжения кристаллохимических параметров решетки KДП с некоторыми органическими люминофорами. На основе квантово-химических расчетов усредненного радиуса молекул люминофоров, анализа величин зарядов их диссоциированных ионов, а также экспериментальных результатов по вхождению молекул в кристаллы предложен критерий когерентного сопряжения встраиваемой молекулы с узлами решетки. Данный подход может быть предложен для модифицирования органическими люминофорами различных водорастворимых кристаллов. en Інститут загальної та неорганічної хімії ім. В.І.
