Characterization of the Nanoporous Template Using Anodic Alumina Method

Abstract EN

Porous anodic aluminum oxide (AAO) is deposited on a 5 cm × 5 cm tin-doped indium oxide (ITO)/glass substrate, and the AAO/ITO/glass structure thus formed is used to reduce the amount of unreacted Al inside the AAO template, thereby reducing the transmittance of the AAO/glass structure.

The enhancement of transmittance is achieved by modulating the diameter of the pores and varying the applied bias.

The proposed AAO can be used at a high applied bias (up to 120 V) to improve the uniformity of the current density.

Following pore-widening treatment and posttreatment annealing, the morphologies and transmittance of the AAO/ITO/glass structure were also investigated.
