Bimolecular relaxation kinetics observed in radiation-optical properties of Ge–As(Sb)–S glasses

Numerical parameters of decaying bimolecular relaxation kinetics are analysed for radiation-optical properties of chalcogenide glasses within ternary stoichiometric As2S3–GeS2 and Sb2S3–GeS2 as well as non-stoichiometric As2S3–Ge2S3 systems in dependence on their composition. It is shown, that the observed compositional dependences of bimolecular relaxation parameters have a monotonic character in the glasses of both stoichiometric systems, while the anomalous extremum-like behavior is observed in the vicinity of average coordination number close to 2.7 in non-stoichiometric glasses.
