Abstract: The present work describes the effect of Sb addition on the optical properties of As₄₀Se₆₀ chalcogenide thin film. The addition of Sb (7%) results (As₄₀Se₅₃Sb₇) chalcogenide with no structural change. Both As₄₀Se₆₀ and As₄₀Se₅₃Sb₇ films have amorphous nature though we have added Sb semi-metal. Non-direct electronic transition was found to be responsible for the photon absorption inside the investigated films with Sb incorporation in place of Se. It was found that, the optical band gap E_g decreases while the width of localised states (Urbach energy) E_c increases. The XPS core level spectra changes with the addition of Sb clearly interpret the optical properties change due to Sb addition.
