Abstract. A physicotechnical fundamental of the multilayer photoluminescent media
development has been considered. The quantum yield and relaxation time of
luminescence were found as most significant values of the recording material. Organic
pyrazoline dyes were adopted due to their appropriable characteristics. Possibility of the
further luminescent material parameters increase while performance dye molecules in the
white nanostructured zeolite matrix by components mixing and laser annealing was
proposed. Experimental results with 60 % of quantum yield gain and relaxation time
quadruple decrease was obtained. Using the received materials in plotting the
identification luminescent elements based on the optical disc cover procedure has been
determined.

Nowadays organic luminescent dyes are widely accepted
in various branches of industry including multilayer
photoluminescent information recording [1, 2], where
the quantum yield and relaxation time are most
significant values. In this area, the neglect of recording
material properties blocked up the development of the
most perspective projects, e.g., like a famous 100 Gb
FMD-ROM prototype disc of the “Constellation 3D” [1],
where the signal-to-noise ratio and reading rate were
found unacceptable.
Luminescent readout signal is spatially isotropic
and optical head get just a part of the probing beam
energy (α = dΩ/4π, where dΩ is reflected ray recept
angle). Luminescence quantum yield η, absorption factor
kA, detector system and land exposure loss coefficients
(kRS and kLE, respectively) are other reasons of the
luminescent signal low power:
P = P0 η (dΩ/4π) kA kRS kLE. (1)
It was calculated that the signal power for different
registration luminescent materials could be 0.2 to 2.4 %
from the power of the reflective disc readout signal.
Thus, in this case the problem of low signal-to-noise
ratio is a major one, while the main way of its solving is
in synthesis of the dye with a high luminescence
quantum yield. The luminescence relaxation time, on the
other hand, is a main feature of the data reading rate and,
therefore, selection of the appropriable registration
material will allow getting this parameter up to that of
the modern optical discs.
Toward this end, the following organic pyrazoline
dyes [3, 4] were investigated: 53SM (base pyrazoline
UV dye with 5 % addition of polymethylmethacrylat),
59HM (pyrazoline “orange-red” dye with 5 % addition
of polymethylmethacrylat), 53SC (pyrazoline UV dye
with 5 % addition of polystyrene), 59HС (pyrazoline
“orange-red” dye with 5 % addition of polystyrene).
Most of them were accepted as a very effective
registration media with a quantum yield of luminescence
up to 60-70 %, the relaxation time less than 100 ns, wide
spectrum of the photoluminescence (Fig. 1) and
moreover possibility of two-photon absorption.
Nevertheless, further research demonstrated a potential
for the additional improvement of these characteristics.
Our new method is based on the performance of organic
dye molecules in the white zeolite matrix. The series of
experiments confirmed theoretical consideration that the
zeolite submicron pores divide a bulk of the dye into the
nanoparticles with a set of improved optical charac-

teristics. And the quantum yield gain is the main of the
predicted ones, because nanoparticles of any
luminescent material are characterized by the ratio:
)1(1 2Dβη += , (2)
where β is a constant and D is the diameter of
nanoparticle.
The main luminescent intensity peak for pyrazoline
dyes grows up to 20-30 % (Figs 3, 4), but comple-
mentary laser annealing increases this parameter at least
twice causing complete pores fill with the dye. The
growth of the luminescence quantum yield is caused by
the quantum size effects that change molecular energy
structure of the dye, and thus some forbidden transitions
are turning to partially allowed ones. Organic dye
absorption growth in this case is also concerned with an
appearance of the new allowed transitions. In the zeolite
submicron porous structure excited molecules relax to
the lower levels and thus absorb larger quantities of the
light. Theoretically, these effects can also cause the rise
of additional luminescent peaks, which was
demonstrated for some types of the pyrazoline dyes. It
was investigated that for complex synthesized pyrazoline
dyes are crucial ∗ππ cross-linking with an active energy
hydrogen bond with a typical effect of transmission
spectrum infrared shift (Fig. 2).
The calculated maximal value of preferred
luminescence relaxation time is lτ = 100 ns. Such a
relaxation time value would allow reading data from the
luminescent media with a rate equal to multispeed
compact disc drive, but for approaching of the rate of
DVD or even Blue-Ray Disc drives one must further

decrease this value. Our experiments showed that the
relaxation time value for pyrazoline dyes at the
exponential level is e

of the zeolite decreased the luminescence relaxation time
twice ( e

Synthesized pyrazoline dyes also get there
application at such a specific area of the information
recording as an optical disc counterfeit protection [3-5].
A complex protection procedure includes 1D and 2D
luminescent barcodes, unreadable sectors zone and
luminescent cover with microtext. For plotting all the
identification elements, proposed were pyrazoline dyes
with additional IR laser light local bleaching. The dyes
with zeolite were used in formation of the cover, because
this element was developed for visual identification
under UV light and material with extremely high
quantum yield level of the luminescence could provide
the best ergonomics. On the other hand, on the working
surface one should use pyrazoline dye with the highest
level of transparency for reliability of the readout
process.
Thus, synthesis of the luminescent material
based on the performance of organic pyrazoline dye
molecules in the white zeolite matrix enabled to obtain
the favorable abilities in the area of the information
recording and security. Theoretical considerations of the
high quantum yield and low relaxation time of resultant
material got entire experimental confirmation.
