    Optical-spectroscopic signature of radiation-induced instability in glassy arsenic sulphides
    (Видавництво Львівської політехніки, 2012) Shpotyuk, Ya.; Polovynko, I.
    Optical changes caused by 60Co g-irradiation are studied in glassy-like As2S3. 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.
