Summary:Preparation of pre-patterned alumina substrates using bottom-up techniques compatible with nanotechnology applications is still a challenge. We present a novel methodology to achieve superior order in 'anodic' alumina with large interpore distances by a convenient one-step anodization process. The use of transparent insulators renders such anodic layers applicable as templates for nanostructured photovoltaic or photoelectrochemical devices. We prepare arrays of cylindrical pores featuring large periods (460 nm and 600 nm) by anodization of aluminum. A self-ordered monolayer of nanospheres drives the subsequent pore ordering and yields a quality of order significantly improved with respect to the traditional two-step anodization procedure.
