Abstract

The nanoporous alumina films were prepared by two-step anodic oxidation in ethanol-oxalic acid mixture. The scanning electron microscope (SEM) measurements reveal that the synthesized films have highly ordered pore arrangements. The photoluminescence (PL) measurements show that the PL intensity of the film has been significantly improved comparing with the films prepared in the oxalic acid

and the PL intensity increases with the ethanol concentration. The reasons for the above experimental phenomena were discussed combining the infrared reflectance spectroscopy with X-ray photoelectron spectroscopy. This work will provide a new idea for doping in the nanoporous alumina film and improving its luminescence property.
