PHOTOLUMINESCENCE WITHIN THE FUNDAMENTAL ABSORPTION EDGE OF MIXED CdSe-CdS CRYSTALS (in Russian)
The photoluminescence of large crystals of CdSe-CdS, monocrystals of CdSe, and large crystal layers of CdSe and CdS was investigated at the self- absorption edge. All specimens had hexagonal structure. The spectra were taken at 77.3 and 4.2 deg K with a spectrometer of 50 and 13 A/mm dispersion at 7600 A. At 4.2 to 77.3 deg K the emission spectra of mixed layers is dampened, the legibility of complex line emission is disturbed (at 77.3 deg K the mixed layer line emission appears on a hand and only with 96% CdSe-4% CdS does it retain a doublet structure); and, the intensity of short-wave lines is sharply reduced. As the temperature is increased from 4.2 to 77.3 deg K, the doublet and triplet components increase and long-wave components diminish. (R.V.J.)
