TITLEi The Absorption of Light by CdS-Crystals (PogloBhcheniye sveta kristallami CdS) PERIODICALs Doklady Akademii Nauk SSSR,19r,,7,Volpll4,Nr 3,pp(,520-523(USSR) ABSTRACTo The authors investigated the spectra of the monocrystals of the hexagonal modification of CdS at 20A 0K in polarized light. The samples were produced by evaporation of Cd and S in an 3 + H -atmosphere argon-atmosphereg by evaporation of Cd in a H 2 and by evaporation of CdS (recrystallization). Sampies with different boundaries and surface finish were investigated and the thickness of the samples varied betwfien I and 100 The spectra were investigated by a polsization-microprojeotor. Two components of the spectrum which correspond to the pola- rization of the light vector along the hexago-.ial axis and vertical to it were simultaneously fixed on the photo-plate by the use of a crystal or Iceland spar. The scheme of the ab- sorption spectrum of the CdS-orystal in polarized light is illustrated by a diagram. The spectrum contains 10 rather Card 1/3 narrow bands (in the interval 20400 - 20600 cm-') and some 20-114 -3-19/60 The lbsorption of Light by CdS-Crystals wider bands over a contl uous background. In the short-wave range at about 21100 cm-7 the continuous absorption begins. Striking is above all the weak polarization of the bands Nr 9 and Nr 10 which is distinctly to be noticed in both com- ponents of the spectrum. These two bands can only be connect- ed with the absorption by the atoms of the layer near to the surface or with asymmetric defects* The second peculiarity Is also importanti The intensitlee of the bands from Wr 1 to Nr 10 as well as the polarization and the position of these bands in the spectrum can be different not only in different samples but also in different ranges of one and the same sample. Details of the behavior of the different bands are given. The lumingseence spectra of CdS-monocrystale at a tem- perature of 20,4 K were also investigatedl in this connect'on a green and also a blue luminescence were observed. The bands of this luminescence are probably in no connection with the exiton-states# but with eleotron-transitions near the defects. There are I figure and 7 references# 4 of which are Slavic.

PERIODICAL: Optika i Spektroskopiya, 1958, Vol.IV, Nr.7. PP - 348-353 (USSR) ABSTRACT: Luminescence was recorded on the side of a cadmium sulphide crystal plate o-pposite to that on which-the exciting light fell. A E;laSB spectrograph KS-55 was used. Luminescence was excited by means of a mercury lamp. Crystals were cooled by means of liquid hydrogen or helium and measurements were made at 200K. Monocrystals of CdS were grown by sublimation of powdered CdS. or by synthesis of Cd and S vapours. Over 50 monocrystalline samples were studied, The luminescence spectrum was found to ,rary from sample,to sample. Usually two regions were observed: a "green" an~ a "blue" one. "Green" luminescence is 100 cm:--L wide; "blue" luminescence consists of narrow lines overlapping with the absorption lines of a CdS crystal. In some samples intense Card 1/3 orange luminescence was observed; in such samples the 5-7--- 4- -3-10/30 Iaminescence of Cadmium Sulphide C-17S I., als- Irblup," luminescence was absent and the 11green" was weak. Uvially sam les which had intense "blue" luminescence at 20PK had weak Vgreen" luminescence and conversely. 1 In tile "green" ospectrura (19550-17500 cm7 ) two series of bands viere observed. The stronger of these series begins at 19310 cm-1 and contains 5-6 ?inds. The second (weaker) series begins at 19500 cm- and containa 4-5 banda. Usually the fJ-rst series was prosent and tile so-,oud absent. The "green" lumines,3ence was affected by treatment of crystal surface. New bands and changes in tho relative intensities of bands wel,,' ob3erved on et,~hing in 11C1. In the "blue" luminescence 12 band:z were observed in the region 20GOO-1982q cm 1. Many "blue" luminescence bands coincide with lines at the edge of furidamental absorption. Fig-1 gives photographs cf the "blue" lura-i -n escence of two thin monocrystals of CdS. A considerable difference in the spectra of these two samples oan be seen in Fig.l. Fig.2 shows coincidence of the ""blue" luminescence bands vii.th the absorption Card 2/3 bands.

The author concludes that in luminescence of CdS crystals emission of up to six typos of spatially oeparated contros, rolated to crystal lattice defectn, may L-- observod. Two of these types of centres are responsible for the "green" lumines--ence and the other four for the "blue" luraines-.ence. Vibrational stracture in each series of bands is due to the interaction vrith vibraticns of the lattice deformed near an emitting centre. The author thanks V.L. Broude and E.I.
