The effect of Bi on the structural and optical properties of Se{sub 82-x}Bi{sub x}Te{sub 18} glassy alloys is studied, theoretically. Cohesive energy is calculated by using chemical bond approach and is found to decrease with increasing Bi content. Optical band gap of thin films is calculated by Shimakawa's relation. The optical band gap decreases with increase in Bi content.
