Abstract

Sol-gel dip coating method was adopted to prepare Rhodamine-6G doped SiO₂-TiO₂ thin films. Effects of MTMS/TEOS ratio on the crack of the thin films during drying stage were studied. The cracking was greatly decreased with the increase of MTMS/TEOS ratio. Crack free thin films were obtained for the samples with MTMS/TEOS greater than 0.75. The optical absorption and fluorescence spectra of the thin films were recorded. The refractive index increases linearly with the increase of TiO₂ content (20, 40, 60 mol%). The third order nonlinear susceptibility of the Rhodamine-6G doped SiO₂-TiO₂ thin films is (chi) ⁽³) approximately equals 10^-9 esu measured by the generate four wave mixing technique.
