Influence of Synthesis Conditions on the Photoluminescence Properties and Paramagnetic Centers of Porous Alumina Formed in Sulfuric Acid
It is shown that it is possible to control the type and concentration of paramagnetic centers (F+ centers and Al–SO4 molecular groups) in anodic alumina 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.
