The Study of Radiation-Induced Instability in the Glassy Arsenic Sulphides by Optical Spectroscopy

Article Preview

Abstract:

Optical changes caused by 60Co γ-irradiation are studied in glassy-like As40S60. The observed long-wave shift in the range of fundamental optical absorption edge accompanied by increase in transmittance is explained as a manifestation of complicated nature of radiation-induced structural transformations associated with coordination topological defects and additional shrinkage input from natural physical ageing.
