Abstract
The challenge in making films specifically for optical devices lies in obtaining transparent films with sufficient crystallization and preferential orientation of the crystallites with respect to the substrates. Transparent BaTiO3, thin films have been prepared by the sol-gel process in our laboratory. The precursors were barium isopropoxide, titanium tetrabutoxide with isopropanol as solvent, and glacial acetic acid and acetylacetone as catalysts. By firing, transitions from amorphous to polycrystalline of the films took place in the temperature range of 600 - 650 degree(s)C. In order to obtain crack-free, more condensed films with preferential orientation and good electro-optic properties, strontium titanate single crystal (100) substrate is recommended.
