dc.description.abstract From scientific point of view, because the composition of chalcogenide glass (ChG) determine the kind of structural units and the mean coordination number, in the present work the amorphous films of the As2Se3:Sny (y=0÷10.0 at.% Sn) chalcogenide system was investigated. The transmission and photoconductivity spectra, photo-darkening relaxation and holographic characteristics of the amorphous films under study were measured. It was demonstrated that with increasing the concentration of tin in amorphous As2Se3:Sny the effect of persistent photoconductivity was observed. The values of degree of modifications of the refractive index Δn under light irradiation and heat treatment were revealed. As a result of investigation of the photoinduced phenomena it was established that the more sensitive to light irradiation are the amorphous films of As60Se40 and As50Se50 compositions which exhibit big modifications of the refractive index ( (n n) 0.394 ). The correlation between the photostructural and holographic characteristics was established. en_US
