Abstract

119Sn and 129Te (129I) Mossbauer spectroscopy showed that chalcogen-enriched Ge100 − yXy (X = S, Se, Te) glasses are constructed of structural units including two-coordinated chalcogen atoms in chains such as Open image in new window and Open image in new window . Germanium in these glasses is only tetravalent and four-coordinated, and only chalcogen atoms are in the local environment of germanium atoms. Chalcogen-depleted glasses are constructed of structural units including two-coordinated (in Open image in new window chains) and three-coordinated chalcogen atoms (in Open image in new window chains). Germanium in these glasses stabilizes in both the tetravalent four-coordinated and divalent three-coordinated states, and only chalcogen atoms are in the local environment of germanium atoms.
