POROUS ANODIC ALUMINA MEMBRANES WITH XEROGEL FOR LUMINESCENCE AND PHOTOCATALYSIS

Abstract

The method of synthesis of porous anodic alumina membrane with amorphous xerogel corresponding to chemical content of SrTiO3 is reported. The membrane was prepared in oxalic acid electrolyte and revealed intensive blue photoluminescence with a broad band at 400 nm after heat treatment at 700 °С either with or without xerogel. Possible influence of oxygen vacancies in the structures membrane/xerogel on their luminescence and photocatalytic activity is reported.
