dc.description.abstract The transmission spectra of bulk and thin films of (As4S3Se3)1-x:Snx in the visible and infrared (IR) regions were investigated. Doping of As4S3Se3 chalcogenide glass with Sn impurities essentially reduce the absorption bands of S-H (Se-H) and H2O located at ν=5190 cm-1 and ν=3617 cm-1, respectively. The amorphous (As4S3Se3)1-x:Snx thin films exhibit photoinduced effects under the light irradiation with photon energy above the optical band gap (hν≥Eg), that make its perspective materials for registration of optical and holographic information. The modification of optical parameters (optical band gap Eg, absorption coefficient α, refractive index n) under light irradiation and heat treatment of the amorphous thin films with different amount of Sn was studied. en_US
