Antimony (Sb) based chalcogenides have an adequate potential in nonlinear and optoelectronic applications. In the present work, a new quaternary Se70 Ge10Te20-xSbx (x = 3, 6, 9, 12, 15, 18) system has been studied theoretically for various important physical parameters. The impact of variation of Sb (replacing Te) on the system has been discussed in terms of average coordination number, cohesive energy, heat of atomization, and theoretical optical band gap of the system. Almost all the parameters are found to vary linearly with the variation in Sb content.
