Effect of Annealing on Structure and Physicochemical Properties of (Ge20Se18Te62)100 – xIx, Where x = 0, 8

Effect of Annealing on Structure and Physicochemical Properties of (Ge20Se18Te62)100 – xIx, Where x = 0, 8

In this paper we report the structural, thermal, microstructural and infrared transmission properties of iodine doped (Ge 20 Se 18 Te 62 ) 100 – x I x (where x = 0, 8) chalco-halide glasses. The density of the specimen has been calculated experimentally. Differential thermal calorimetry shows a sing...

Zusammenfassung:In this paper we report the structural, thermal, microstructural and infrared transmission properties of iodine doped (Ge 20 Se 18 Te 62 ) 100 – x I x (where x = 0, 8) chalco-halide glasses. The density of the specimen has been calculated experimentally. Differential thermal calorimetry shows a single glass transition temperature but two crystalline peaks. The role of annealing (503 and 593 K for 2 h) has also been taken into account to investigate the structural, microstructural, and infrared transmission properties. X-ray diffraction study has revealed that on annealing there is an origin of hexagonal Te and orthorhombic GeSe 2 microcrystals which are further supported by scanning electron microscopy.
