Abstract : A connection is established between the lin spectr= of the absorption
edge and the spectral distribution of photoconductivity of a CdS
crystal. According to the concepts concerhing the exciton mechanism of
photoconductivity, each line in the absorption spectr= corresponds to
a maximum of photoconductivity. When CdS (T =:77-30K) is exposed to
light so polarized that the E-vector, the optical axis c of the crystal,
and the direction of the incidence of the ray lie in th-e same plane
(the E vector and the axis c form thereby a small sharp amqgle), in the
spectral distribution'of the photoconductivity displays narrow maxima
at 4869" 484o, 4820, iind 4710 A.- The-first three maxim are in good
agre;;;;L with"the lines in the absorption spectru6-. In'the case when
E is pitrpeiadicular to 6, the wavelengths 4869, 484o, and 4820A corres-

ductivity. Such a phenomenon was observed earlier by the authors in the
case of Hg3~ (Referat Zh. Fizika, 1956, 2316) and is connected, in
their opinion, with an increAse in the absorption coefficient when E
is Perpendicul to a. If the coefficient is very large., all the light
is absorbed near the surface, which may cause a reduction in photo-
conductivity owing to the increased exciton, annihilation.

The conclusion is reached that optical excitation of exitons causes
internal PE. Wide structureless PE mri"a in the region of absorp-
tion edges of ordinary and singular beams are probably connected
with continuous absorption. This shows that PE arises also on light
absorption in continuous spectra. However in such a ease the PE can
be caused by excitons formed by recombination of electrons and holes.
Occurence of recombination is confirmed by exciton radiation of these
crystals on excitation in principal lattice. With another orienta-
tion of c, E and 1, in lieu of PE peaks at the location of absorption
lines are found PE dipa, which are attributed to surface absorption
of light. The effecis of infrared and red brightening on PE curves
have been investigated.

TITLE: Absorption of Light in Crystals of Mercury Halides
(Pogloshcheniye sveta v kristallakh galogenidov rtuti)
PERIODICAL: Izvestiya Akademii Nauk SSSRj Vol, XX1, #2, pp 220-
224, 19571, USSFj Seriya fizieheskaya
ABSTRACT: Excited states of solids are manifested in absorption
spectra of orystals by discrete structure at the long
wavelength border of internal absorption. The role
of the lattic* in the existence and properties of
exciton levels can be experimentally detected by
two methods: t
1. Studying and comparing absorption spectra of
crystals of different chemical compounds possessing
similar lattices;
2. Studying absorption spectra of crystals of dif-
ferentimodifications of the same substance possessing
polymorphism, property; this method allows to detect
the effect of crystal lattice on exciton levels "in
Card 1/4 the pure form."

TITLE: Absorption of Light in Crystals of Mercury Halides
(Pogloshcheniye sveta-v kristallakh galogenidov rtuti)
The article describes results of studying absorption
spectra in mercu'ry halides HgJ29 HgJ and HgBr 2'
The absorption spectrum of tetragonal modification of
HgJ has a complicated and diverse structure (lines,
banis, continuous absorption steps extendinj inta
wide sp;8trum region from 59330 to 3,725 (a
T = 77. K). Basing on the Dykman and Pekar theory,
the narrow lines in the absorption spectrum can be
ascribed to the excitation of non-polarizing excitons
in the HgJ crystallic lattice. The broad bands can
be ascribeq to the formation of polarizing excitons
connected with the higher excitation levels in the
HgJ2 crystal.
In the absorption spectra of the rhombic modification
of Hgj2, no discrete structure was observed. Thm
rhomble lattice of HgBr 2 is wholly isomorphic With
the rhombic HgJ2 lattice and their absorption spectra
are indentical. Th"e 'risults indicate the strong
Card 2/4 effect of lattice structure on crystal exciton levels.

TITLEs Adsorption of Light in Crystals of Mercury Halides
(Pogloshchaniye sveta v kristallakh galogenidov rtuti)
The difference between tetragonal and rhombic Hgj
modifications stems mainlyfrom a difference in tRe
geometry of lattices. -
Adsorption spectra of HgJ were also studied. Structure
was not detected in its monocrystals; in the thin
polycrystal layers a broad band preceding continuous
adsorption spectrum Was discovered. The band center
situated a,* a wavelength of 4,240 k( at T = 77-3*y)-
It can be ascribed to the excitation 6f polarizing

The luminescent spectrum of PbJ 2 crystals consists of several
groups of lines and 4 equidistant bands# which resemble a so-
called "edge emission" observed with other crystals kCdS, ZnS,
ZnO).
There is a great similarity in luminescence spectra of PbJ 2P
US and CdSez besides the resonance lines, their spectra
show a group of emission lines and an equidistant band group
with long wavelengths ( "edge emission").
Resonance emission lines are to be considered as the lumines-

sion" is not as yet clear. The bibliography lists 9 references

TM- The shape of photoconductivit~ spectral curves in crystals with
discrete absorption edge structure at 77.3 K was studied on CdS, Hg12, and Pb12
single crystals. For these crystals. the maxima of photoconductivity were found
to correspond to the discrete absorption lines ascribed to excitons. The shape
of the absorption spectra and of the photoconductivity curves in CdS and HgI 2
chiefly depends on the mutual orientation of the crystal axis c and the electri-'
cal vector E of the exciting light. In H912 crystals, when the absorption coeffi-
cient in the lines is large, a self-reversal of the maxima of photoconductivity
is observed, which is related to the increased annihilation of excitons near the
surface. The constant infrared illumination reduces photoconductivity; however,

ABSTRACT: The author reports a discovery, at 770K, of a luminescence
line spectrum in LiF prepared from monoorystals subjected
to X-ray radi&tion for tens of hours (only visible
coloration is produced). The luminescence was excited by
ultraviolet light from a SVDSh-1000 mercur lamp and recorded
by means of a glass speotrograph with --,..,,40 I/mLm dispersion
in the yellow region of the spectrum. Two typical spectra
are shown in Fig. a and 0; Fig. 9 is the iron spectrum used
for calibration. At 770K, apart from the well-known wide
red and green bands, the following narrow Itatomidil iines were
found: a group of four equidistant (A\-' -247 cm- ) lines at
569.8, 578.0, 586.2 and 595.0 m/k (of eleotron-vibrational
Card 1/3 origin); several lines between the latter, e.g. 581.0 and

583.0 m/tt; lines at 562.7, 553.5 and 546.0 m~k ; a line
at 531.6 mAx which appears only after further irradiation
with ultraviolet light; lines at 534.0, 444.0 mA-%- ete,
which are present only in some samples. These i~zes
di6appear on heating to room temperature. Their intensities
,Vary from sample to sample (the samples were X-ray irradiated
for various lengths of time) and certain lines were present
in some samples but not in the others. The author suggests
that these lines may be closely related (resonance) to the
absorption lines which were observed in strongly colored
UF at low temperatures by Pringsheim. and others (Refs.
2p3) but no explanation of their origin is offered.

ABSTRACT: Elastic uniaxial compression or extension of a cubic crystal removes
"orientational degeneracy" of energy levels of anisotropic contras,
oriented along G. axes. This is true both for the ground and excited
states of these contras. Such comprassion or extension should produce
splitting of individual absorption or luminescence bands which are due
to transitions between levels of the anisotropic centres. It is shown
that splitting of such bands can give information from vhich the
orientation of the anisotropic contras in the lattice and the nature
of the oscillators, used to describe absorption and luminescence of
these contras, can be found. For this purpose the contras should possess
narrow spectral bands and a system of levels sensitive to small elastic
deformations of the crystal lattice. It is also required that the
magnitude of the displacement of such levels should depend on the
orientation of tho contras with respect to the direction (P) of the
card 1/2 applied stress and that this displacement should be different for

TEXT: The authors studied the effect of deformation on the crystal spectra,
which are related to 1) optical transitions between energy bands and
2) excitation of exciton states. The effect of uniaxial compression of
CU20 crystals at 770K on their spectra of the long-wave main absorption
edge, the lines A = 6164, W85, and 6125 A inclusive, was studied. The
Cu20 single crystals were compressed in the direction of the C 4? C3' C2
symmetry axes (the direction of compression is indicated by P), and the
absorption spectra were taken perpendicular to P (in the direction L). The
results are briefly discussed and sh-ova in a figure. Pictures were also
taken in polarized light. The main characteristics of the splitting

that one of the energy bands is single, and the,other is triply-degenerate
(in the extreme case at r = 0). This experimental result is in agreement
with theoretical investigations (Ref. 11) in which it was shown, on the
basis of group-theoretical considerations, that the valency band (in
connection with the 2p levels of 02-) is triply-degenerate, and that the
free band (4s levels of Cu) is single. There are 1 figure and 11

TEXT: This is a very detailed report on studies made on monoaxially
compressed Cu 20 single crystals~ As a consequence of this deformation, an
aniBotropic polarized splitting of the longwave edge was observed to take
place along with an exciton structure of the Cu 20 absorption spectrum.
Multiplicity, amount of splitting, and polarization in the spectra were
examined with different direations of compression. The method used for the
investigation was similar to the one described in Refs. 13,14. The
specimens were about 1~ 2X 4 mm -large platelets placed in a special press
inside a Dewar vessel (770K). The spectra were taken in polarized
(MP, E 1P) and unpolarized light by an vicn-51 (ISF-51) spectroscope,
dispersion-v5A/mm, and a Y~ -85 (UF-85) camera. The spectra were all taken

The spectra in the figures are described in the text and certain charac-
teristics are pointed out. The magnitude of the splitting is in all cases
(LIP; PlIC 41 Pilo 30 Pilo.) directly proportional to the compression
pressure. The polarized splitting was calculated, and the theoretical and
experimental splitting amountsL were intercompared (,6 =Y -))0, 2)0 being the
position of the line in the free crystal). The agreement is satisfactory.
From results obtained it was possible to infer the character of the energy
levels. The results can be explained by assuming that the triple de-
generacy of the valency band in deformation is removed at 7 = 0. The
final part of the paper under consideration deals with the effect- of the
crystal deformat ion upon the yellow exciton series of Cu 20 (V. T. -

this investigation). It was found that at P11C4 the set is sharply shifted
in the direction of longer waves; the same, but less markedly, applies to
PI(CY and at P 11C2 a polarization effect appears in addition to this
shift. The uniform shift of the lines allows the conclusion that deforma-
tion has an effect upon the position of the band, but not-upon the
individual exciton levels; a relationship was found, furthermore, to
exist between the hydrogen-like exciton levels with n=~2 and the degenerate
band. A. G. Zhilich is finally thanked for discussions on theoretical

TEXT: When examining the absorption spectrum of monoorystalline samples of
Ca 20 (T - 770 K) the authors of the present paper detected the effect of
anisotropic light absorption (X- 6125 A), which is unusual in the case of
cubic crystals. It was found that in the spectrum of light passing through a
Cu 0 lamina the intensity of these absorption lines is not equal in two
ar?itrarily chosen states of polarization which are perpendicular to each
other. The degree of polarization and the integral intensity vary from opeci-
men to specimen and also when the direction of the beam changes. A sufficiently
large CU20 crystal was bred and used to determine the dependence of intensity
and polarization of these lines upon the direction of the beam in the crystal

lattice. Thin sheotsg which were differently oriented relative to the orystallo-
graphic axeeg were out out of this crystal. It was found that the intensity and
the degree of polarization of the lines under consideration are fully determined
by the orientation of the beam relative to the crystallographic axes. The
results obtained are described by means of the spectrogram shown in Fig. 1'and
the scheme shown in Fig. 2. Herefrom it may be seen that the spatial distribu-
tion of intensity and of the state of polarization has some elements of cubic
symmetry. When taking account of polarization only (neglecting absorption
intensity) it is possible to determine seven "optical" axes along which absorp-
tion is isotropic. The anisotropy of the absorption lines is ascribed by the
authors to electric quadrupole transitions since the observable dependence of
intensity and polarization upon the direction of light inside the.crystal
corresponds to the spatial field distribution of an electric quaftupole system.
In discussing the results obtained here the authors refer to papers by
S.I. Pekar et al. (Refs. 12 and 13) in which it was pointed out that optical
anisotropy of cubic crystals associated with the occurrence of excitons is
theoretically possible* Furthermore, a paper by VoLo Ginzburg (Ref. 14) ia
referred to, in which spatial light dispersion was taken into consideration.

The detection of quadrupole transition makes complementary demands on the theory

and quadrupole transitions allowed. In conclusion, reference is made to a
model devised by A.G. Zhilich (Ref. 2) for these transitions. The authors

Elliott's theory (Proc. Internat. Confer. Semicond., Prague, 408, 1960;
Phys. Rev. 124t 340, 1961) of the connection between these edges and
indirect exciton transitions in the band n-1 (combined exciton-phonon
transitions). The good agreement between this theory and the experimental
results speaks in favor of the theory. The symmetry type of the phonon
involved is assumed to be P- It can also be assumed that exciton
12'
migration takes place in Cu 20., There are 1 figure and 1 table.
