Abstract:

Anodic aluminum oxide (AAO) membranes with 100 mu m thickness were synthesized in oxalic acid solution under constant current density. Grown samples were annealed in 500-1250 degrees C range for 5 h in air. Average pore diameter was evaluated using quantitative analysis of SEM images and appeared to be within 78-86 nm diapason. It was found there was a broad emission band in the 350-620 nm region of photoluminescence (PL) spectra in amorphous membranes which is attributed to F-type oxygen deficient centers or oxalic ions. It was shown that intensive red emission caused by Cr3+ (696 nm) and Mn4+ (680 nm) impurities dominates in PL of AAO samples with crystalline alpha- and delta-phases after annealing at 1100-1250 degrees C temperatures.
