Bismuth oxide (Bi2O3) films are deposited on glass substrates using the spray pyrolysis method at different substrate temperatures within the range 250-300-350-400°C. The transmittance and absorbance show a clear change with temperature, namely, the transmittance is increasing with temperature, and this is accompanied by a decreasing in absorbance with temperature. The energy gap is varied from 2.5 eV for the films prepared at 250°C to 2.8 eV for the films prepared at 400°C. Finally, the grain sizes for Bi2O3 are calculated; they are appearing as sizes of 70.30, 66.25, 61.73, and 56.77 nm at temperatures of 250, 300, 350 and 400°C, respectively, revealed from x-ray spectrum by using the Debye-Scherrer method.
