Abstract

IR impurity absorption spectra in 4000-1000 cm-1 (2.5-10 mm) region for chalcogenide glasses of pseudobinary stoichiometric As2S3(Sb2S3)-GeS2 and non-stoichiometric As2S3(Sb2S3)-Ge2S3 cross-sections are studied. The compositional features of the main absorption bands of the various impurity structural fragments are compared for the investigated As-based and Sb-based glassy systems..

Keywords

Chalcogenide glasses, IR optical properties, Impurity absorption.
