| Abstract | ||
| NanoSilver doped (2%,4% and 6%) (NiO) thin films were fabricated on glassslide substrates at (4000C) by spraying method using a solution containing Nickel (III) oxide, Silver chloride and water. The effect of silver nanoparticles (AgNP’s) on the structural,morphology and opticalproperties of (NiO) thin films were studied, the structural properties werestudied by X-ray diffraction (XRD). The results show that all the samples have a cubic structure. After (Ag) doping, the intensity of the diffraction peaks became smaller than the undoped(NiO) thin film. The topography properties were studied by atomic force microscopy (AFM) and scanning electron microscopy (SEM) while optical properties were studied byUv-vis spectrophotometer. The optical transmittance has been decreased.On the contrary, the optical band gaps of (Ag) doped (NiO)thin films increase as the(Ag) content increased. Single oscillator energy, dispersion parameters and Urbach energy have been investigated which effected by the increasing of (Ag) content. | ||
