Abstract: In this study, the effect of adding antimony trioxide (Sb₂O₃) on optical properties of (PVA-PVP) has been studied. Samples have been deposited by adding different concentration Sb₂O₃ by using casting method. Absorbance and transmittance spectra has been recorded in the wavelength range 250-1100 nm. The outcome display that the transmittance decreased as Sb₂O₃ content increased. Optical constants of PVA-PVP-Sb₂O₃ composites increase with the increasing of Sb₂O₃ content. The energy band gap of PVA-PVP-Sb₂O₃ composites decreased as the Sb₂O₃ content increased.
