An ordered array of isolated alumina nanotubes was obtained using an anodizing method of -based films, which was composed of three steps: anodization of a -based film under a constant dc voltage in sulfuric acid to form a porous alumina film, followed by further anodization under a pulse voltage for a short time to detach the alumina film from the substrate, and final immersion of the alumina film into dilute phosphoric acid for a few minutes to form an ordered nanotube array. This kind of ordered arrays is expected to have important applications as templates in fabricating ordered nanostructures.
