Nanocomposite (S3Sb2) x (S2Ge)100−x chalcogenide glasses: structural and physical properties

Abstract

The current paper shows the different effects of the incorporation of sulfur (S)–antimony (Sb) on both the structural and physical properties of nanocomposite (S3Sb2) x (S2Ge)100−x chalcogenide glass for x = 15, 30, 45 and 60. Different physical parameters such as lone-pair electrons, average coordination number, interatomic spacing and field of strength increase with the addition of antimony–sulfur, while other parameters such as heat of atomization and polaron radius show the reverse behavior. The stoichiometry (R > 1) shows that the studied compounds are rich in chalcogen atoms, and an increase in lone-pair electrons indicates the good glass-forming ability of the studied compound.
