Physical and Optical Properties of Ge10Se90-xSbx Glasses

Atul K Kukreti, Shilpa Gupta, Manish Saxena and Nikhil Rastogi

Chalcogenides glasses doped with antimony (Sb) have shown remarkable potential in nonlinear and optoelectronic applications. In search of finding the optimised glass for the use in infra-red optics the new ternary Ge10Se90-xSbx (x = 0, 3, 6, 9, 12, 15, 18, 21, 24) system has been studied theoretically for variation in physical parameters. Transmission spectra for Ge10Se80Sb10 have been used to study the absorption and refractive index of the material. The compositional variation of Sb (Replacing Se) on the system has been studied in terms of average coordination number, cohesive energy, glass transition temperature and transmission spectra of the system.
