Preparation and investigation of composite SiO2-TiO2 films

Journal of Applied Spectroscopy Aims and scope

Abstract

SiO2-TiO2 films [Si:Ti = 1:(0.06–2.3)] are obtained by the sol-gel method. The structural and photoluminescent properties of the films and powders heat-treated at different temperatures are studied. It is shown that after 700°C the composite consists of TiO2 crystallites that are structurally similar to anatase and distributed in an amorphous SiO2 matrix. The photoluminescence spectra have maxima at 450–500 nm. The photoluminescence intensity depends on the treatment temperature and TiO2 content.
