Fe2O3 Thin Films Prepared by Spray Pyrolysis Technique and Study the Annealing on its Optical Properties

Full Text PDF


Fe2O3 thin films that doped by NiO were obtained on glass substrates by the chemical spray pyrolysis technique, and annealed at 450 °C and 500 °C. 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 °C. Absorption coefficient and extinction coefficient increase with increasing annealing temperature.
