Abstract：Titanium dioxide based organic-inorganic hybrid film containing azobenzene was prepared by a sol-gel technique and a spin-coating method. The surface morphology, transmission mode, refractive index, thickness and photochemical structural properties of the hybrid film were characterized at different heat-treatment temperatures. The results show that the hybrid film is a good optical waveguide material with the smooth and dense surface. Also, the refractive index is adjustable when the heat-treatment temperature is lower than 300 ℃. The absorbance of the sample irradiated by a ultraviolet light at 365 nm and a visible light at 450 nm was examined to investigate the optical switching property of the hybrid film. It is indicated that the hybrid film has good optical switching properties. In addition, the hybrid film with a fatigue resistance also has promising application prospects in photonics.
