“…Chalcogenide glasses are of peculiar interest in optoelectronics due to their outstanding optical properties. [1][2][3][4] Vitreous arsenic sulfide (As 2 S 3 ) possesses both high refractive index and wide transmission range. 5,6 Generally, either pnictogens (Sb, Bi) or halogens (Br, I) are introduced into the glass matrix to increase its refractive index.…”

The ability to predict the influence of dopants (such as antimony) on the shortrange 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 AsI 3 molecules justified by Raman spectroscopy and XPS. Further antimony introduction (As:Sb<2:1) leads to the substitution of arsenic by antimony in -S-As-S-polymeric chains, leading to SbSI crystallization justified by XRD. The resulting two-dimensional schematic diagrams represent the AsSI-SbSI glasses short-range structure and show the mechanism of arsenic by antimony substitution.

“…In addition to this, As 2 S 3 is a fine matrix for cations of rare earth and transition metals that provide the vitreous material with special electrical, thermophysical, mechanical, and magnetic properties [3]. The introduction of post transition metals (specifically, bismuth [4]) into As 2 S 3 allows one to synthesize glasses with even more practi cally relevant properties [5]. The present study was aimed at characterizing the physicochemical proper ties of glasses obtained by introducing bismuth in an ionic state (as an alternative to its introduction in an elementary form).…”

Chalcogenide glasses of the As-S-Bi-Br system are synthesized, certain physicochemical prop erties (density, microhardness, glass transition temperature, and transparency range) of these glasses are determined, and the refraction index is calculated based on the principle of additivity of covalent refractions. The thermally activated mobility of bismuth cations in the glass lattice and the partial transition of bismuth into a subvalent state are revealed by X ray photoelectron spectroscopy.
