| -- | The present work deals with the deposition of CuO thin films on substrates of zinc oxide by a simple and cheap technique such as chemical bath (CB). In first, a set of ZnO thin film was prepared using optimized spray pyrolysis conditions in order to devote the films for ions copper adsorption from aqueous solution. Two sources (zinc acetate and zinc chloride ) are considered as deposition parameters. LaCl3 7H2O was used with different rate of doping.The Structural, morphological and optical results confirm that the films are ZnO hexagonal wurtzite structure with a strong orientation along (002) with excellent optical properties. Further, the application of thin films as adsorbent was studied by Cu(II) adsorption from aqueous solution 0.2M. The obtained ZnO:La 1wt .% films are an effective adsorbent for removing Cu(II) with high adsorption capacity (87%). Thin films of copper oxide were obtained after annealing the ZnO:La substrates at temperature ranging between 200 - 350 ʻC. Structural, morphological, and optical characterizations were performed on the CuO films. The structural analysis of the later shows that the obtained films are polycrystalline, they exhibit a monoclinic structure. The preferential orientation is strongly related to the experimental parameters studies. From the optical characterization, it was inferred that the deposited films have suitable optoelectronic properties for the photovoltaic applications since they present a good absorption in the visible range |
