ABSTRACT

Copper oxide (CuO) nano flakes were successfully prepared by a co-precipitation method.  X-Ray diffraction patterns confirm that the films have polycrystalline nature with monoclinic structure. The SEM analysis revealed that golf ball structure with randomly oriented surface feature was observed for the CuO nanoparticles deposited at the high substrate temperature. The EDS analysis showed the presence of Cu and O in the films. In summary, various results indicate that this technique is a low temperature, cheap, and fast method for the producing CuO nanostructures. The average particle size was 21 – 34 nm. The crystallite size CuO nanoparticles of the observed from the SEM data matched with the estimates obtained from the XRD data. The results obtained indicated that the co-precipitation method is a promising low temperature, cheap and fast method towards the preparation of CuO nanostructures.
