Abstract

Light-induced structural changes of g-As40S60 and g-As45S55 were probed by macro FT-Raman and photon-energy dependent micro-Raman spectroscopy. We hypothesize that some new observed features in the Raman spectra of these glasses are related to transformations of As4S4 molecules possible through the m-As4S4 intermediate. At the same time, other processes, connected mainly with the layers, composed of pyramidal AsS3 structural units, take place. These new observed Raman modes and their possible interconnection to changes of the glassy structure are discussed.
