【 摘 要 】

We report the annealing effects on the morphological and structural properties of Cu2O films electrodeposited on Cu substrates from an aqueous solution containing copper acetate and lactic acid. The Cu2O/CuO layers has been constructed by electrodeposition of p-Cu2O layer on the modified surface of Cu substrate followed by formation of the CuO layer by annealing from 100°C to 300°C. The morphology and structural analysis was performed using optical microscope, AFM and XRD respectively. The result showed that increasing the annealing temperature resulted in the increment of the Cu2O grain size from about 96 to 201 nm. AFM reveals the precipitation of CuO grains on the Cu2O layer by annealing in air at 300°C, and completely covered the surface of Cu2O layer.
