On the Temperature Behavior of Optical Gap in Arsenic Sulfide Glasses
Abstract
Temperature behavior of optical transmission in the fundamental optical absorption edge region is studied for a broad range of As–S glass compositions covering the entire glass-forming interval. It is shown that temperature dependences of optical gap values for all bulk glasses can be well fitted by the one-phonon approximation based on Bose–Einstein statistics. Correlation of fitting parameters with thermodynamic data and compositional structural development published earlier is discussed.
