Popis: Numerical parameters of decaying bimolecular relaxation kinetics are analysed for radiation-optical properties of chalcogenide glasses within ternary stoichiometric As 2 S 3 –GeS 2 and Sb 2 S 3 –GeS 2 as well as non-stoichiometric As 2 S 3 –Ge 2 S 3 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.
