Characterizationof pure and Nano(Ag) doped(NiO) thin films obtained by Chemical Spray Pyrolysis

الملخص

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.
