Abstract

Radiation-induced dynamic effects were studied in chalcogenide glasses of quasibinary (As2S3)1-x(Sb2S3)x (0 ≤ x ≤ 0.3) system using optical spectrophotometry technique in the region of fundamental optical absorption edge. It was established that dynamical component of post-irradiation decaying gradually grows with Sb content in the studied glasses, the kinetics of the observed changes being non-exponential tending towards monomolecular one. The observed changes were explained by compositional dependence of free volume in the studied system.
