Abstract: In this work, thin films of nickel oxide (NiO) were deposited by a simple and inexpensive technique, which is spraypyrolysis on ordinary glass substrates heated to a fixed temperature of 500 °C, from a solution containing nickel nitrate hexahydrateas a precursor dissolved in distilled water with deferent values of concentrations. The NiO thin films obtained were characterized todetermine the structure with X-ray diffraction technique (XRD), the absorption domain (UV-Visible Spectroscopy), and the surfacemorphology (SEM). The X-ray diffraction patterns confirm the presence of NiO phase with preferential orientation along the (111)direction. The optical gap for nickel oxide calculated with a concentration of 0.1 M from the measurement of optical absorption is 3.6eV, which is quite comparable to the value of the ratio.
