Abstract:

In this paper, the influence of the precursors of nickel oxide (NiO) on the properties of ZnO/NiO nanocomposites thin films, grown by spray pyrolysis method, has been investigated. The nickel sulfate, nickel chloride and nickel nitrate have been used as precursors of NiO, each precursor has been mixed with Zinc oxide (ZnO)’ precursor to elaborate ZnO/NiO nanocomposites thin films with the method mentioned above. The aim of this paper is to confirm the similitude of precursors in the nanocomposites. For this reason, and to reveal this goal, some techniques were used as the structural analysis by X-ray diffraction (XRD) which a high intensity has been detected corresponds to the ZnO / NiO films with nickel chloride precursor, UV-Visible characterization depicts the presence of a maximum adsorption band appears in the ultraviolet range, the morphological characterization with Atomic Force Microscopy (AFM) reveals the roughness and the different grain size of particles, the big one of the latter agree, also, with to nickel chloride precursor used. The values of optical band gaps Eg are globally equal with high value noticeable agree with films that prepared with nickel chloride and zinc chloride precursors. The results obtained confirm the aim and a good agreement with the latter were found.
