Glass formation region and X-ray analysis of the glassy alloys in AgGaSe2+GeS2 <=> AgGaS2+GeSe2 system

Abstract

A region of glass formation was found during melt quenching from 1273 K in the AgGaSe 2 +GeS 2 AgGaS 2 +GeSe 2 system. It is localized along the binary GeSe 2-GeS 2 system. Characteristic parameters (T g , T c , T m) were determined for the glassy alloys, and T gr and K G were calculated using them. The radial distribution functions were calculated using the integral Fourier transformation based on X-ray scattering curves. The average interatomic distances within the first and second coordination spheres were determined.

“…Phase equilibria in the reciprocal system AgGaS 2 + GeSe 2 Û AgGaSe 2 + GeS 2 were investigated, and the glass formation region was determined [8]. An In our previous works on these glasses, we investigated the main structural units of the glass-forming matrix by Raman spectroscopy, as well as photoluminescence spectra under excitation by 532 and 980 nm wavelengths [4,9].…”
