Paper Abstract

The application of sol-gel thin films on the transparent hologram is introduced in this paper. The plastic films coated with titanium dioxide using sol-gel process were embossed to form special patterns in micrometer scales and thus the transparent holographic thin films were made. AFM, SEM, ellipsometer and electrophotometer were used to characterize the TiO2 coating and the transparent hologram. The results show that the titania coating has nano-porous structure and the refractive index of the titanium dioxide coating is about 1.9. The diffraction efficiency of the titanium dioxide derived transparent holographic thin film is about 2.0%.
