INTRODUCTION
Data on the optical characteristics of a gas-discharge
plasma on mixtures of zinc diiodide vapor with helium
are important for the diagnosis and optimization of the
spectral and energy characteristics of sources of
spontaneous (excilamp) and coherent radiation (lasers).
Mixtures of zinc diiodide vapor with inert gases can be
promising working media for creating environmentally
friendly spectral radiators in the visible and ultraviolet
spectrum range. Investigations of the optical
characteristics of such radiators on mixtures of zinc
diiodide vapor and helium under gas-discharge plasma
conditions and optical pumping are presented in [1-5].
In this case, the repetition rate of the generator pulses
that excited the plasma was ≤100 kHz. To create
powerful narrow-band sources of visible and ultraviolet
radiation, it is of interest to study optical characteristics
at higher frequencies of plasma excitation, which was
the purpose of our studies. In this paper, studies are
made of the optical characteristics of atmospheric
pressure gas-discharge plasma on mixtures of zinc
diiodide vapor and helium and a small addition of
molecular nitrogen at a pump pulse repetition rate of
130 kHz.
1. THE TECHNIQUE AND METHODS OF
THE EXPERIMENT
The technique and methods of the experiment were
similar to those used in the study of the optical
characteristics of a gas-discharge plasma ofan
atmospheric pressure barrier discharge on mixtures of
zinc diiodide vapor with helium [6].
2. RESULTS AND DISCUSSION
Typical oscillograms of current and voltage are
shown in Fig. 1. In each half-period of the applied
voltage on the oscillogram of the detected current, a
series of sharp picks of different amplitudes and about
the same duration was observed on the displacement
current curve. Each current pick is caused by a set of
filamentary microdischarges - filaments that occur in
the discharge gap and are statistically distributed in
time.
Fig. 1. Oscillograms of voltage and current pulses of a
gas-discharge plasma of a barrier discharge in
a ZnI2 / He = 0.5 Pa/150 kPa mixture
The oscillogram of the current pulses is asymmetric-
in the positive half-cycle, the first burst had a much
larger amplitude than the others, and in the negative
half-cycle the amplitude of all the bursts was
approximately the same. This is apparently due to the
fact that with increasing frequency in the DBD on the
mixture, the role of the factors associated with the
discharge geometry significantly increases, namely, the
surface areas of the electrodes are very different, since
the discharge occurs in the "cylinder-wire" system, the
dielectric is covered only one electrode of the radiator,
and in one case the charge transfer occurs first through
the dielectric barrier, and then through the plasma, and
in the other way around - first through the plasma, and
then through the dielectric.
A typical survey spectrum of the radiation of DBD
plasma on a mixture of zinc diiodide vapor with helium
is shown in Fig. 2. In the spectra obtained in the visible
range, a band with a maximum at = 602 nm was
distinguished, which had a poorly-resolved vibrational
structure and corresponded to the В2+
1/2
Х2+
1/2electron-vibrational transition of the ZnI
molecule [7].

Fig. 2. The survey spectrum of the radiation of a gas
discharge plasma of a barrier discharge on mixtures:
1 – ZnI2 / He = 0.0003 Pa / 150 kPa (cold mixture);
2 – ZnI2 / He = 0.5 Pa / 150 kPa
The bulk of the radiation of ZnI(BX) molecules is
concentrated in the range of 590…608 nm. The shape of
the ZnI (BX) band is similar to the spectral bands
corresponding to the BX transition in mercury
monohalides, namely: a steeper increase in intensity
from the long-wave range anda slow decline in the
short-wavelength region. At atmospheric pressure of the
mixture, due to the completion of vibrational relaxation,
the transitions occur mainly from the lower vibrational
levels of the excited electronic state. The width at half-
height for the spectral band of ZnI (BX) was 15 nm,
which agrees with the results of [1], where the optical
pumping of the ZnI2/Ar mixture by ArF laser radiation
was used. Also in spectra there were atomic zinc lines -
5s 4p (468.0, 472.2 and 481.0 nm) triplet, 4d 4p
(636.2 nm) line [8] and molecular iodine bands, the
most intense of which was band I2 (D'-A ' ) with a
maximum at = 342 nm [7]. The intensity of the
atomic lines and the brightness of the molecular bands
strongly depended on the temperature of the working
mixture. The intensity of the zinc lines increased with
increasing temperature, while the brightness of the
bands of molecular iodine decreased. The brightness of
the molecular band was understood as the area under the
curve on the spectrum.In the spectral region
315…425 nm, molecular nitrogen bands corresponding
to the electronic-vibrational transition
C Bu g
3 3 of the second positive N2 system were
also observed. They were manifested in the spectrum
due to burningof the discharge (parasitic) in the air
between the outer surface of the quartz tube and the
grid. At a temperature <100…120 0C, in the range
420…480 nm, bands that are identified with the
emission of I2 molecules (BX) were observed (see
Fig. 2). In the emission spectrum of the DBD (see
Fig. 2), the intensity of the helium atomic lines
noticeably decreased as the working mixture warmed
up. This regularity is due to a decrease in the electron
temperature in the discharge with an increase in the
concentration of readily ionizable particles, in
particular, zinc diiodide molecules and zinc atoms. [9].
When the helium partial pressure in the ZnI2 / He
mixture was increased from 102 to 200 kPa, the
brightness of the ZnI (BX) radiation increased
approximately three times without signs of saturation
(Fig. 3). Such a dependence can be caused by an
increase in the temperature of the working mixture and,
in turn, by an increase in the partial vapor pressure ZnI2.
Addition of nitrogen to the ZnI2 / He mixture (the inset
in Fig. 3) led to a monotonous decrease in the intensity
of the ZnI molecules, since the energy of the discharge
is expended on additional channels, including
vibrational excitation of molecular nitrogen.
The emission of spectral bands and barrier discharge
plasma lines on a mixture of zinc diiodide vapor and
helium is probably observed due to the following
reactions: [10, 11]:

where M is the concentration of quenching molecules
and atoms (ZnI2, He,), respectively, E1,2 – energy
difference in reactions (4), ∆Е3, ∆Е4-energy difference
in reactions (7) and (15).
In addition, the formation of ZnI (B) molecules can
also occur in electron-ion and ion-ion recombination
reactions. But the contribution of such processes is
insignificant because of lower concentrations of the
initial components [10].
Reactions (1) and (2) are known as the main sources
of exciplex molecules of zinc monoiodide (ZnI*), which
rate constants are not known at the moment. It can be
assumed that they are within the limits of 10-15 m3/ s and
10-17 m3/s, respectively, since the specific radiation
power in the spectral band of the exciplex ZnI*
molecule (Fig. 4) is close to the specific radiation power
in the spectral band of exciplex molecules mercury
monoiodide and mercury monobromide [12]. In
addition, molecules of zinc monoiodide can be formed
in reactions (3) due to the excitation of molecules of
zinc diiodide to state D in collisions with electrons (D-
state is the sum of several states that are located
between 7 and 13 eV (ionization threshold ZnI2) [2, 10].
326 ISSN 1562-6016. ВАНТ. 2018. №6(118)
Emission from the D-state of ZnI2 is not observed, since
this state rapidly dissociates with the formation of
electronically excited ZnI* molecules in C and D-states
[10]. They are quenched in reaction (4), leading to a
high population – the state
21

[10]. The reaction of the collision of molecules of zinc
diiodide with electrons (6) is a channel for the formation
of molecules of zinc monoiodide in the ground
state

our estimate, is ~ 10-15 m3/s. Electron-vibrational
transitions

/
B (
2/1
2X ) ofzinc
monoiodidemolecules lead to the emission of spectral
bands with maximum intensity at a wavelength of
λmax. = 602 nm (reaction (6)) [10]. Emission of spectral
bands with a maximum intensity at a wavelength
λmax. = 342 nm is caused by the electron-vibrational
transition D ' A' of iodine molecules (reaction 9), and
the emission of spectral bands at λ = 420…480 nm is
caused by the electronic-vibrational transition B X of
iodine molecules (reaction 10) [10]. Excited iodine
molecules are formed in reaction (8). Excited zinc
atoms are formed due to the passage of reactions (8) due
to the large effective cross section for the dissociative
excitation of molecules of zinc diiodide with electrons
[11]. The reaction (13) is responsible for the excitation
of the atoms of the helium buffer gas. An important role
in the emission of spectral bands and lines belongs to
the quenching processes from which emission occurs
both by zinc diiodidemolecules (reaction 7) and by
atoms of the buffer gas helium (reaction 15), because of
which the radiation intensity decreases, the rate
constants of which have the value 1.7 ∙ 10-9 m3 / s and
~ 1.5 ∙ 10-11 m3 / s [2].
Measurement of the average radiation power W of
the radiator was carried out at a total pressure of
150 kPa (see Fig. 4). After the discharge was switched
on with increasing temperature, the average power
initially increased during 12 minutes after which a slight
decrease in W for 8 min was caused by a decrease in the
intensity of emission of inert gas lines and spectral
bands of molecular iodine (see Fig. 3). Then the radiator
entered the regime in 20 minutes and W was stabilized.
Under these conditions, the maximum value of the
average radiation power per unit area in the visible
range was 34 mW/cm3 (see Fig. 4), the efficiency with
respect to the power input into the discharge was ~ 8 %.

CONCLUSIONS
Thus, as a result of complex studies of the optical
characteristics of atmospheric pressure DBD plasma
atmospheric pressure on mixtures of zinc diiodide vapor
with helium, intense emission of a spectral band with a
maximum at = 602 nm of exciplex molecules of zinc
monoiodide, the bulk of which is concentrated in the
wavelength range 590…608 nm. In addition, spectral
bands of molecular iodine were detected, the most
intense of which was the band I2 (D'A ') with a
maximum at = 342 nm and spectral bands of the
ВХ electron-vibrational transition in the wavelength
range 420…480 nm, and also the zinc line – a triplet of
5s 4p (468.0, 472.2 and 481.0 nm) and a 4d 4p
(636.2 nm) line.
The average radiation power per unit volume was
34 mW/cm3 in the wavelength range
Δλ = 550…650 nm, the efficiency with respect to the
power input to the discharge was ~ 8 %.
A radiator based onatmospheric pressure DBD plasma
with high-frequency pumping of a working mixture of
zinc diiodide vapor with helium can be the basis for
creating a self-heating excilamp that emits in the orange
spectral range. Scaling of the working area of the barrier
discharge will make it possible to use the radiator in
biotechnology, medicine, etc.
