摘要：
Synthesis of (Ag2S)(x)(As2S3)(1-x)superionic glasses for x<0.2 are carried out. The spectrometric studies of optical absorption edge in (Ag2S)(x)(As2S3)(1-x)glasses are performed in the temperature range 77-390 K. Optical absorption edge of (Ag2S)(x)(As2S3)(1-x) glasses with addition of Ag2S is strongly smeared and has an exponential shape.The influence of temperature and composition on the absorption edge behavior, parameters of optical absorption edge and electron-phonon interaction as well as ordering-disordering processes in (Ag2S)(x)(As2S3)(1-x) superionic glasses are studied.
