Optical properties of some [(As2S3)0.5:(As2Se3)0.5]1-x:Snx chalcogenide glasses

The transmission spectra of bulk and thin films of [(As2S3)0.5:( As2Se3)0.5]1-x:Snx in the visible and near infrared (IR) regions were investigated. The doping of As2(S, Se)3 chalcogenide glass with tin impurities essentially reduces the absorption bands of S-H (Se-H) and H2O located at ν = 5190 cm-...
