Qısa məlumat

Complex experimental studies are made of optical phenomena, EPR spectra, Raman scattering, and heat capacity of pure and Nd-doped TlGaS2 single crystals in a wide energy (2.1 to 2.7 cV) and temperature (1.8 to 300 K) range. An anomalous iemperature dependence of optical spectra, the decay of free excitons, the EPR in the temperature range from 3.6 to 16 K, and the Raman scattering are observed and phase transitions of second order (75 K), and of first (75 K) and second (90 K and above) order in doped and pure TlGaS2 crystals, respectively.
