Summary: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. 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.
