Paper Abstract

The results of optical properties study of porous aluminum oxide films, fabricated by anodizing in a water solution of a sulfuric acid and modified by thermal annealing on air at temperature T≥800°C are reported. On the basis of the comparative analysis of the received data it is shown that a photoluminescence in near UV and visible regions for aluminum oxide anodized in a sulfuric acid solution originates from the divacancies of oxygen (F2, F+2 and F2+2 centers) and sulfates - ions do not render essential influence on luminescent properties AOA in researched spectral area. For samples annealed at T = 1300 °C, intensive narrow strips determined *see abstract on paper* by the radiative transitions (2E → 4A2) in ions of Mn4+ (678 nm) and Cr3+ (694 nm), replacing ions of Al3+ in octahedral positions of α-Al2O3
