Determination Of Assi-Sbsi Glasses Short-Range Structure Via Raman Spectroscopy, Xps And Xrd

The ability to predict the influence of dopants (such as antimony) on the short-range structure of As-S-I glasses has the potential to help design glasses with modified properties. In the present work, the short-range structure of As-Sb-S-I glasses has been investigated along AsSI-SbSI section of fixed sulfur and iodine concentrations and equivalent arsenic by antimony substitution. At high arsenic content (As:Sb ≥ 2:1) antimony substitutes arsenic in AsI3 molecules justified by Raman spectroscopy and XPS. Further antimony introduction (As:Sb
