摘要: ZnO nanostructures were grown on an Au seed layer by a hydrothermal method. The was deposited ion sputter Si (100) substrate, and then the with different precursor concentrations ranging from 0.01 M to 0.3M at growth temperatures 0.3 of concentration. FE-SEM (field-emission scanning electron microscopy), XRD (X-ray diffraction), PL (photoluminescence) carried out investigate structural optical properties nanostructures. morphologies are shown conditions images. density changed significantly as changed. increased concentration increased. barely nanostructure has highest density. pattern shows (100), (002), (101) peaks, which indicated structure wurtzite structure. higher intensity lower FWHM (full width half maximum) peaks observed temperature , crystal quality.
