Fe₂O₃ thin films that doped by NiO were obtained on glass substrates by the chemical spray pyrolysis technique, and annealed at 450 ºC and 500 ºC. The effect of annealing on optical properties was studied by recording the absorbance spectra using UV-Visible spectrophotometer. The refractive index decreases with increasing annealing temperature, such as an optical band gap that decreases from 2.68 eV before annealing to 2.58 eV after annealing of 500 ºC. Absorption coefficient and extinction coefficient increase with increasing annealing temperature.
