Glass Formation in the As–Se–SbBr₃ System

Glass formation in the As–Se–SbBr₃ system is studied. Glasses are synthesized by melting a batch of As, Se, and SbBr₃ at a temperature of 700°C. The density of the glasses and optical absorption in the IR region of the spectrum are measured. The glass transition and crystallization temperatures are determined using differential thermal analysis (DTA). The structure of the glasses is studied using Raman spectroscopy. It is proposed that antimony bromide enters the glass as isolated molecules, without exchanging bromine with arsenic selenide. The studied glasses are promising for the production of low-melting IR adhesives, lenses, and windows for various IR optoelectronic devices using the precise pressing method.
