Nanocrystalline Cu,CuO and Cu2O thin flims were synthesized by Electroless (EL) deposition method by controlling the pH from 11 to 14 at 70o C. The crystallinity, purity, morphology and structural features of the as-synthesized films were chracterized by X-ray diffraction (XRD), Field Emmision Electron Microscope (FESEM), Transmission Electron Microscope (TEM). The results showed that the concentration of NaOH plays an important role for the growth of nanocrystalline Cu, CuO and Cu2O thin flims having grain morphologies changing fron sperical to cubic. A growth mechanism was proposed and discussed in details for the grain morphological changes during depostion. |
