Long-term radiation-induced optical darkening effects in chalcogenide glasses
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2016, Vol 19, Issue 4
Abstract
In this work, it is reported that the -irradiated (2.41 MGy accumulated dose) glasses As2S3 (2 mm thick) and Ge15.8As21S63.2 (1 mm thick), both measured 10 years after -irradiation, exhibit radiation-induced optical darkening effect (i.e., long-wave shift of fundamental optical absorption edge). In the case of As2S3 glass, the observed long-term radiation-induced optical darkening effect is well comparable with that reported in literature for -irradiated (3 MGy accumulated dose) glass As2S3 (1.5 mm thick), measured directly after -irradiation. In view of practical application, this finding demonstrates the possibilities for development of innovative chalcogenide glass based long-term dosimeter systems with stable and control parameters. A possible general criterion for mechanisms of long-term radiation-induced structural changes in chalcogenide glasses has been also considered.
