Radiation-induced physical ageing in network arsenic-sulfide/selenide glasses
Effect of radiation-induced physical ageing is investigated by differential scanning calorimetry method in AsxSe100−x (10 ≤ x ≤ 42) and AsxS100−x (30 ≤ x ≤ 42) glasses. Obtained results are compared with conventional physical ageing at normal conditions. Significant radiation-induced physical ageing...

Summary: | Effect of radiation-induced physical ageing is investigated by differential scanning calorimetry method in AsxSe100−x (10 ≤ x ≤ 42) and AsxS100−x (30 ≤ x ≤ 42) glasses. Obtained results are compared with conventional physical ageing at normal conditions. Significant radiation-induced physical ageing is recorded for glassy AsxS100−x within 30 ≤ x < 40 range, while AsxSe100−x glasses from the same compositional interval do not show any measurable changes in DSC curves after γ-irradiation. Observed difference in radiation-induced physical ageing in arsenic-sulfide/selenide glasses is explained by a greater lifetime of γ-induced excitations within sulfur-based network in comparison with selenium-based one. |
