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. Int his 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, antimony substitutes arsenic in AsI3 moleculres justified by Raman spectroscopy and XPS. The resulting two-dimensional schematic diagrams represent the AsSI-SbSI glasses short-range structure and show the mechanism of arsenic by antimony substitution.
