Structural Characterization and Physical Parameter Assessment of Al-Modified (SbTe2)Se Chalcogenide Glass

Physical properties of the chalcogenide material play a major role in specifying their possible applications. In the current work, multicomponent Al(SbTe2)1–xSex (x = 0.1, 0.2, 0.3, 0.4) chalcogenide glasses have been prepared through melt-quench technique, and physical properties were also investigated. Structural and morphological features have been studied employing X-ray powder diffraction and SEM-EDX techniques. Average coordination number and constraints, as calculated, reveal that the material is an optimum glassy system. Furthermore, the occurrence of lone pair in the composition is assessed. Further investigations regarding the glass transition temperature, the prepared material is examined with the help of Tichy-Ticha and Lankhorst methods.
