Local structure of copper zinc oxide nanoparticles synthesized from single step solid state synthesis of the prepared different Cu concentrations in the starting precursor reactance copper zinc acetate salt. The phase structure of the copper zinc oxide nanopowder product was confirmed by X-ray powder diffraction (XRD). The particle size and morphology were investigated by field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). Short range crystal fine structure was investigated by X-ray absorption spectroscopy (XAS). The result demonstrate the Cu atom is substitution incorporation in Zn sites of ZnO wurtzite host for using 0.1 and 10 mole% Cu concentration in the acetate precursors. The second phase of CuO nanocluster was present in the Cu doped ZnO structure for the use of Cu concentration 10 and 50 %mole precursor. The radial distribution functions in short range order from Zn atom, points to a high concentration of O and Zn vacancies in all samples which correlates with the distortion of local symmetry ZnO cluster compared with ZnO standard, and corresponding to the small particle size reveal by TEM image. A higher disorder corresponding to the interpreted XRD result in terms of crystallinity degree which is likely originated by a disorder of surface and interface effect, the prepared samples showed much small particle size which is much high distorted ZnO cluster and the highest defect O and Zn vacancies is the sample prepared form 1.0 mol% Cu precursor. As a result, these copper zinc oxide nanoparticles indicated feasible promising candidate as a high quality material in many applications which need high active surface and high phase interface with fine homogeneous nanoparticle.
