Porous anodized aluminum oxide (AAO) membranes with different diameters are fabricated using anodization of Al foils in the sulfuric acid, oxalic acid and phosphoric acid solutions. The photoluminescence (PL) properties of the corresponding AAO membranes are investigated. Based on morphology observations and PL measurements, it is revealed that the peak position of the observed PL band has an evident dependence on pore geometrical structure of AAO, and the PL spectra of AAO membranes are associated with the acid impurities and the singly ionized oxygen vacancies. The intensity change of PL bands for the acid impurities and the singly ionized oxygen vacancies is further discussed on the basis of the PL behavior of the AAO membranes with different pore-diameters. These results reveal that the PL properties of the AAO membranes are very sensitive to their chemical and pore-structures, which are closely related with their anodizing conditions. The present work may be helpful in understanding of the PL properties of the AAO membranes with different pore-diameters formed in different acid solutions..
