Popis:	ZnO nanostructures were grown on metallic zinc nanocones by thermal oxidation. The metallic nanocones are prepared by argon ion beam sputtering utilizing a capillaritron ion source. The aspect ratios of zinc nanocones are found to be dependent on ion beam energy and substrate temperatures. By maintaining the substrate temperature to be less than 60°C, the aspect ratio of zinc nanocones increases from 1.2 to 2.7 as ion beam energy increases from 6to12keV. Zn nanocones with aspect ratio larger than 25 are obtained by utilizing a 12keV ion beam and allowing the substrate to increase to ∼180°C by in situ ion beam heating. Thermal oxidation of zinc nanocones results ZnO nanowires and nanoblades grown outwardly from the shank. This provides a convenient route for the fabrication of ZnO nanowires for field emission flat panel display and dye-sensitized solar cell applications.ZnO nanostructures were grown on metallic zinc nanocones by thermal oxidation.
