Abstract
SnO2 nanowires were grown on Au (gold) covered nickel foam substrates by thermal evaporation at 750 ℃, 800 ℃ and 850 ℃ respectively. The growth behavior of the nanowires were investigated by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The element binding states of the samples were studied by X-ray photoelectron spectroscopy (XPS). Photoluminescence (PL) properties were chartered by Fluorescence Spectrometer at room temperature. The results reveal that growth temperature has a significant influence on the morphology, size and density of SnO2 nanowires. At 750 ℃, SnO2 was granular. SnO2 nanowires with high densities were generated at 800 ℃ and 850 ℃. The photoluminescence properties at room temperature were studied. It was found that with the increase of growth temperature, the photoluminescence properties of SnO2 increased significantly with the increase of the production of SnO2 and the concentration of oxygen defects.
