Abstract: (5201 Views)
Cupric oxide (CuO) thin films were prepared by spray pyrolysis technique on glass substrate with various volumes (40, 50 and 70 ml) of copper acetate precursor solution. Samples were characterized by FESEM images, XRD and UV-Vis. spectra, and also I-V characteristics. We found all samples are polycrystalline nanostructures mainly grown along (002) direction. Also it was revealed that the one which is grown with the precursor volume of 50 ml with optimum structural (highest crystallite size and lowest defect density), and optical (lowest band gap and highest optical absorbance) condition have the optimum photoconductivity property in the visible range.
