Porous anodic alumina membranes (AAMs) with the 200 nm pores were successfully prepared electrochemically from Al sheets embedded H3PO4 solution. We found that the fitted voltage for the anodization is 160 V, and the concentration of the electrolyte is 0.1 M. Photoluminescence (PL) measurements of AAMs showed an ultraviolet emission at 320 nm, which originated from ionized oxygen vacancies (F+ centers).

A comparative study of self-ordering behaviour of anodic alumina films fabricated in a series of diluted (down to 0.05 M) oxalic acid electrolytes allowed developing a relationship between the supporting electrolyte concentration and self-ordering voltages for the formation of porous oxide materials.
