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.
