It is shown that it is possible to control the type and concentration of paramagnetic centers (F centers and molecular groups of Al-SO) in anodic aluminum oxide and the intensity of dye photoluminescence (using rhodamine B as an example) in its pores by varying the temperature of the sulfuric acid-based electrolyte. The obtained samples are promising for the development of optical sensor platforms.
