Crystal Structures and Properties

The local environment of sulfur in amorphous As2S3Sb2S3Tl2S was studied by XAS at the sulfur K-edge. Variations in shape and position of the white line are attributed to changes in the nature of the chemical bond, the metalsulfur bond lengths, and the homogeneity of the metalsulfur bond length distribution. The variations of the white line parameters, position and line width, with sample composition reveal the different influences of the glass-forming arsenic sulfide and antimony sulfide and the glass modifying thallium sulfide.
