摘要：

Ternary chalcogenide glass systems of Se80Te(20-x)Inx, where x= 0, 5, 10 wt.%, were synthesized via fast quenching of their melts. Bulk samples were ground into fine powder and thermally evaporated onto silica glass substrate, under vacuum, in order to obtain homogeneous thin films. DSC analysis of bulk samples revealed the presence of small endothermic peak, that identifies the glass transition temperature T-g, followed by an exothermic peak that defines the amorphous-crystalline phase transition T-p. These results confirmed the amorphous nature of the bulk samples. XRD analysis confirmed the amorphous nature of the studied thin films. Inclusion of indium in the glass matrix contributed to elevating refractive index and showed wide transmission window in the visible and near IR regions. Linear and nonlinear optical parameters are calculated and discussed in terms of the glass composition. Results of refractive index, first and third order susceptibilities nominate the studied thin films for applications in IR waveguides and sensors. (C) 2020 SECV. Published by Elsevier Espana, S.L.U.
