Optical, Thermal and Topological Characterization of Quaternary Se65Ge15Te20-aSba Chalcogenide Glasses

Se-Te based chalcogenide glasses have been found suitable for optical memory devices due to their distinct amorphous-to-crystalline transformation. In the present work alloys of Se65Ge15Te20-aSba (a = 3, 6, 9, 12, 15, 18) glasses have been synthesized using melt quench technique. Author report investigations leading to optical, thermal and topological properties of these glasses by varying the concentrations of Te and Sb. Glass transition and crystallization kinetics of alloys have been investigated using differential thermal analysis at different heating rates (5, 10, 15, and 20 Kmin-1). The results so obtained verify the usefulness of above composition
