Optical Properties of Silver Doped NiO Films Prepared by Spray Pyrolysis Method
NiO and silver doped (5 and 10 mol %) NiO thin films were fabricated on quartz substrates at 450 C by airbrush spraying method using a solution of nickel nitrate hexahydrate. The effect of silver (Ag) concentration on the structural and optical properties of NiO thin film was studied
by X-ray diffraction (XRD), atomic force microscopy (AFM) and ultraviolet-visible (UV-vis) transmittance spectra. The results show that all the samples have a cubic structure. After Ag doping, the intensity of the diffraction peaks and the transmittance have been decreased. On the contrary,
the optical band gaps of Ag-doped NiO films have been increased.
