Abstract | ||
Chalcogenide glasses are good candidates for applications in the infrared (IR) region [1,2].Chalcogenide glasses are vitreous materials having one or more of the chalcogen elements (Group VI): sulfur (S), selenium (Se), and tellurium (Te). The addition of the network formers (Group IV and V) such as silicon (Si), germanium (Ge), tin (Sn), phosphorus (P), arsenic (As), and antimony (Sb) establishes cross-linking between the tetrahedral and pyramidal units which facilitates stable glass formation [3,4]. Depending on the composition, the chalcogenide glasses are stable against crystallization and are chemically inert. They have excellent thermal stability, and are relatively easy to fabricate. In our present work we have taken the SeO2 powder and then solvent (DMF),put on stirrer for 30 min. The mixed deposited on glass substrate by casting method. | ||
