Spectroscopic Properties of Kiton Red in Hybrid TiO₂/Ormosil Films

TiO₂/ormosil films doped with kiton red have been prepared by the sol-gel method. Spectroscopic properties of the entrapped dye are studied by absorption and emission techniques. The results indicate that the absorption and fluorescence spectra of kiton red depend strongly on the properties of the ormosil matrices. The heat-treatment of dye-doped film leads to the increasing fluorescence intensity and the largest intensity is obtained after heat-treatment of 150°C.
