Abstract
Antimony trioxide (Sb2O3) thin films were prepared by thermal evaporation under vacuum technique, using Sb2O3 powder as evaporate onto glass substrates. The substrate temperature was varied from 323 to 473 K and structural and optical properties of the films were studied. The structural studies of the Sb2O3 thin films indicates the presence of the ?- Sb2O3 with predominant cubic phase. The energy band gap of Sb2O3 thin films was determined from the absolute values of the measured transmittance by assuming a direct transition between valence and conduction band of Sb2O3 thin films.
