ABSTRACT: The purpose of this paper is an electron microscopic inves-
tigation of the structure of some amorphous polymers of various
structures of the molecular -.hains. These investigations were
carried out on polymers of axsenic (ealvarean), polyacryl-
amide, and on the copolymer Dn the basis of Lieth,rlmetacrylate
and metacrylic acid. Therefore, the authors inve3tigate poly-
mers which contain various polar groups in the chain and,
therefore have different intramolecular and inte'.-molecular
interaction forces. The samples for the investigation were
produced by fastening of the polymer solution on a film and
subsequent evaporation of the solvent. The iniestigatione
were carried ovt with direct 18 000 - 20 000-fold electron
Card 1/3 microscopic enlargements. According to these investigations,

On the Forme,tion of Geometrically Ordered 3tructures in Amorphous Polymers
salvarean, polyacrylamide, and the copolymer on the basis
of methylmetacrylate and metacrylic acid form individual
secondary aggregates in diluted solutions. These aggregatos
have the shape of molecular :?ackets of various dimensions
and shapes. For salvarean anti polyaorylamide, the formation
of geometxically regular structures (rectilinear organic.
molecular packets) were obne:rved. The regular shape of these
packets is very noticeable. A packet conpoeed of parallel
molecular chains maintains the flexibility of a single indi-
vidual zhrin. The revolution.3 of the packets by definite angles
may ca%ae the formation of g,.-ometrically regular structures
in amorphous polymers- 3 figires show the microphotographies
of the investigated polymers. These photographs were taken
from concentrated solutions. The results of this paper con-
firmed the following assumption: The structure of the amorphous
polymers has to be considered as a system of ordered molecular
packets. The authors thank P rofessor 111,T. Ya. Kraft and his
fellow workers who placed the spivarsan to the authors' di3-

ABSTRAOT: Capacitance C and tangent of the loss-ang 1e tan
of a capacitor containing a crystal phosphor change when
the latter is illuminated. This effect is called a
photo-dielectric effect (p.d.e.). ; This effect is
observed in-photo-conducting phosphors (Ref.l). Some
authors ascribe p.d.e. to (a) electrons localized at
capture - levels or to the stored light-sum tRef-2),
while others regard (b) photo-oonductivity of the
granular sample to be responsible for this effect (Ref.3).
Irrespective of whether mechanism (a) or tb) is responsible,
on increase of frequency the change in the loss-angle
tangent Atfm~ passes through a maximum, and'the change
in eapacitanoe AC/Co decreases. Dependence of the

should be the same for both mechanisms. The present
authors studied phosphor ZnS-Cu jGu concentration
10-4 g/g; 1100oC) in order to decide which mechanism
is responsible for p.d.o. The optical PrODerties of
the samples were obtained by L*F, Yrasovskaya and
'Yu-L. Lukantsever. All measurements were made using a
Q-meter XB-1. Une capacitor electrode was made of
aluminium foil =d the other of nickel-plated netting
with 575 elements per cm2. The electrode surface was
Om
27 cm2, the phosphor thickness was.2 .g/cn2. A layer
of mica was placed between the sample-and the nickel
electrode, and plate glass on top of the nickel electrode.
Measurements can be made-in a wide range of temperatures
(116-5500K). The phosphor,was excited by the mercury
triplet at 365 mp- Measurements of tanS and 0
were made in the frequency range 3 x 104 - 6 x 106 c/a.
The frequency dependences of tang and G of the
capacitor with ZnS-Cu w~re-Aobtained at various intensities
of the exciting light E and at various totaporatures.:

in Fig.1 are due either to electrons localized at capture

intenhl maximilm due to conductivity in ths) granular sample.
.Fig.2 shows the result obtained at three frequencies at
room temperature (curves marked 1; 2.15 Mc/s; curves

to saturation while A tang passes through a maximum.
Both the frequency and the exeiting-light intensity
dependences of p.d.e* indicate that the effect of the
localized electrons is not important, but that conductivity
of the granular sample is dominant. The frequency
dependence of p.d.e. was also obtained at liquid-:oxygen
temperature both during and after excitation. Luminescence,
and consequently conductivity, after the excitation had
ceased, reached a certain low steady-state value in
9ard 3/6 several seconds. After 2 minutes the p.d.e. fell to 5,%

of its value during excitation, and this effect may
be ascribed to "frozen-in!' llj_~ht-sum or weak residual
conductivity. 1t can be conoluded, therefore, that
above 1160K the localized electrons are re3ponsible
for no more than 5,% of p.d.ee 10ig.3 shows the
temperature dependence of p.d.e. at 100-550011 at different
frequencies and excitinG-light intensities. This
temperature dependence is satisfactorily explained by
changes in concentrations of free electrons, and it is
not due to localized electrons ' The theoretical
formulae obtained for the free-elsotron mechanism
(case (b), conductivity of the granular sample) derived
in this paper are In good ain-eement with the experimental
curves of Fig.3 for A tanT Theory predicts
saturation for 6 C/00, while actually, after reaching
a maximum this quantity decreases (Pi6.3). 11his decrease
is due to temperature quenching of lumlneseence. Again,
the observed behaviour can be explained by changes of
Card 4/6 concentration of free electrons in the region where

quenohing occurs. The latter conclusion was confirmed
by finding the temperature dependence of a p.d.a. for
ZnS-:3n phosphor in which quonching of the blue band
began at 2100K. The results are shown In Fig*4 which
indeed confirms that change of capacitance L U/Co
begins to fall at 2100K. Fi,3.5 shows thormo-curves
of luminescence and p.d.e. of ZnS-Cu phosphor at various
frequencies (thermo-ourves are defined as temperature
dependences when light illumination had ceased). In
obtaining these curves the phosphor was excited for 10
minutes at liquid--O.xygpn temperature. Then the
phosphor was left for 3 minutes In darkness and heating
was carried out at a rate of 0.6 do&/see. Thermo-
curves for luminescence (Fig.5, curve 1) and for p.d.e.
(Fig.5, curves 2-4) were obteined at E = 100%. The form
of t0hermo-curves is ascribed by the present authors to
change of concentration of free electrons in the process
of heating of the phosphor. Thus all the experiments
tend to confirm the hypothesis of the predominant role
of conduction electrons in the photo-dielectriD effect

ABSTRACT% The authors measured the frequency, light, and temperature characteristics
of the photodieleotrio effect (11DE) In ZnS-Cu-phosphor and ZnS-Cu-Fe-
phosphor. The frequency characteristics of Atg6 wid L C for ZnS-Cu
aro in good agreement with those of an equivalent circuit consisting of
two capacitors connected In serLes, one of which is shuntad by an active
realstance. When the exciting light ia switched off at liquid-air
temperatures, the totiLl light diminishes negligibly, while the
luminescence brightneas and, consequently, the conductivity fall off
rapidly, and within two minutes the PDE drops to 5% of the value It
possesses during the excitatior- period. On the basis of these measure-
ments, as well as the results of the temperature dependences of the PDE,
Card 1/2 the authors conclude that conduction electrons are reaponsible for the

on the Cusses of the Photodielectric Effect in Zinc Sulfide Phosphors
greater part of the PDE in ZnS-Cu-phosphor. On investigating the frequency dependences
of the capaoitance of the condenser with ZnS-Cu-Fe-phosphor in the dark and tmder
illumination, it 1:3 found that the difference in & C does not decrease with an in-
crease of frequency as it should (BZhl?iz, 1957, Nr 6, 15617) if the PrE were entirely
caused by a change in grain conductivity during illumination. This allows the hypo-
thesis that in the case of ZnS-Cu-Fe, the PDE Is partially due to localized electrons.
The authors also measured the dielectric constants of these phosphors at a frequency
of 2 Me. In the case of ZnS-Cu the increment in L E - E light - F- dark deplands on
the filler, but not in the case of ZnS-Cu-Fe. The latter circumstance also attests to
the fact that a triie change in F, is observed in the case of the excitation of ZnS-Cu-F,BK

TITLE% The Photodielectric Effec ZnS - Cu, Cc Phosphors
PERIODICALt Fizika tverdogo telap 1960, Vol. 2, No. 9, pp. 2322-2329
TEXT: The authors discuss the various results published in Refs. 1-5
on the photodielectric effect (PEDE). The dependence of the capacity C,
of tan8 (dielectric losses of the capacitor containing a crystal phosphor)
on the frequency W and the light intensity E resulting from these papers
are given in a table. The authors aimed at proving that the PHDE was not
caused by localized electrons. The object uf the investigation was a
ZnS - Cu,Co phosphor having a copper content of 3-10-5 g1g and a cobalt
content of 10-6 g1g, which was pressed into "Ptoroplast-4" in a proportion
by weight of 1s2. The PEDE -was measured at frequencies of between 200 and
5.10 6 cps. For measurements in the acoustic region, aTh-351 (TM-351)
measuring bridge, and at radio-frequencies a K13-1 (KV-1) coulometer was
used. The measurement results are given in the following diagrams:

and Fig. 6, Co as a function of E. Although the dependence of C 0 on E
and temperature apparently indicates an effect of localized electrons, the
authors found an explanation proceeding from the theory of conductivity
and being in better'agreement with other experimental data. In contrast V~/
to the scheme used in the theory of conductivity, the external field does
not vanish in a real phosphor. This is prevented by the diffusion of
electrons and their low concentration. The additional static capacity Co
is caused by the space charge, which is due to the shift of electrons on
the grain boundaries. The author gives the following summary: 1) Under
the action of 'localized electrons, tan ~ should approach saturation with
increasing E. The tan 9 recorded for different E as functions of ~ should
not intersect. 2) If the theory of conductivity is applied, a curve with
a maximum results for tan f - f (E), and the curves tan j - f (w), drawn for
different E, intersect. The experimental results agree with -the conditions

TITLEs Dielectric and photodielectric properties of zinc-sulfide

SOURCE: Fizika tverdogo tela,.v. 6, no. 7, 1964, 2100-2106
TOPIC TAGS: luminor, zinc sulfide optic material, dielectric pro-
perty, photoluminescence, capacitance
A13STRACT: The purpose of the research was to develop a method for
directly disclosing all the in'homogeneities (second pha 'se and bar-
rier layers in the grain itself) that distin,guisb electroluininors
from photoluminors. A test procedure described by the authors else-
where (Izv. AN SSSR, Ser. fiz. v. 26, 475, 1962) was used to test
electroluminors made of EL-460, EL-520, and EL-580 powders from the
"Krasny*y khimik" plant and some electroluminors from GIPKh, The

lpowders,were uniformly distributed in a teflon filler. The dielec-
tric characteristics were investigated in the temperature range
80--370K and the fre'quency range 20--4.5 x 106 cps at 1.5 volts. The
tests have shown that the conductivity causing the peak in the loss
angle is due to the presence of the second phase, and can be either
of semiconductor or metallic character, depending on the concentra-
tion of sulfur above stoichiometric. Exposure to ultraviolet causes
the dielectric properties to display several peaks# the number of
I
which depends on the number of inhomogeneous grain regions with
different conductivities and consequently different relaxation times.'-
It is shown that all three loas-angle maxima observed under ultra-
violet excitation are due to the conductivity in the inhomogeneous
sample. it is concluded that the study of the dielectric and photo-
electric effects by this method would be useful in the investigation
of-inhomogeneous materials such as are used in the construction of
!solid-state devices# Oricla art& hast 5 figures and I formula.
