Fabrication of self-ordered nanoporous alumina for optical and structural characterization Authors Lukas Vojkuvka Lluís F. Marsal Josep Ferré-Borrull Trifon Trifonov Josep Pallarés Abstract We present the fabrication and optical and structural characterization of self-ordered nanoporous alumina membranes. The samples were fabricated using a two-step anodization process. The morphology of the membranes produced using different anodizing conditions was examined with a scanning electron microscope in order to estimate their geometrical properties. The structural properties studied by X-ray diffraction showed that nanoporous alumina is crystallized from amorphous phase to gamma and alpha (crystalline) forms during annealing at 600 ºC to 1200 ºC. The optical transmission spectra of the membranes were measured using a UV-VIS spectrometer in the range of 300 - 1000 nm.
