摘要：

Highly ordered porous anodic alumina (PAA) films are fabricated with high efficiency by stable high-field anodization in oxalic acid/ethanol/water electrolytes at 100-180 V and sulfuric acid/oxalic acid/ethanol/water electrolytes at 30-80 V, giving interpore distances in the range of 225-450 nm and 70-140 nm, respectively. The photoluminescence of PAA films prepared by high-field anodization shows remarkable redshift of the peak position and decrease of the intensity compared to that of PAA films formed by conventional low-field anodization.
