In this paper, the Fe2O3 thin film were prepared with various ratios doping of NiO by spray pyrolysis method on glass substrate temperature 400 °C. The initial solution was including a 0.1 M/L for both NiCl2 and FeCl3 diluted with redistilled water and a few drops of HCl. The effect of NiO-doping on optical properties were studied. UV-Visible spectrophotometer in the range of (300-900) nm used to determine absorbance spectra. The transmittance increased with increasing NiO content in NiO:Fe2O3 thin films, same behavior of extinction coefficient and skin depth. The energy gap increased from 2.45 eV before doping to 2.86 eV after 3% NiO-doping. While the reflectance, absorption coefficient, and refractive index are decreased with increasing NiO content in Fe2O3 thin films.
