Synthesis and Characterization of CuO Nano Particles

The aim of this work is synthesis and characterization of the copper oxide powders "CuO" and its composite thin film of (CuO/PMMA), and ZnO doped CuO powders, by (sol-gel) process (wet-chemistry route, using (Cu (CH
₃
COO)
₂
, H
₂
O), as precursor and DMF (CH

)
₂
NC(OH), as solvent, the obtained powder has undergone a heat treatment annealing to 450°C and 750°C .Various analysis techniques have been used to characterize the CuO powders and its composite (CuO/PMMA) thin films, and doped powders, they are divided into two category: The structural analysis including the X-rays diffraction (XRD), the infrared spectroscopy (IR). Optical properties and band gap of CuO were studied by UV-Vis spectroscopy. The study by the X-rays diffraction (XRD), reveals single phase monoclinic structure of CuO, the average crystallite size of the powder annealed to 450°C is 16.76 nm the study of the optical properties of the CuO/PMMA composite thin films has shown a band gap is estimated to be 3.90 eV.
