Abstract
Transparent barium titanate (BaTiO3) wet gels synthesized by sol-gel processing using high-concentration Ba,Ti-alkoxide solution (1.0 mol/l) were subjected to optical measurements, X-ray diffraction analysis and transmission electron microscope observations. A systematic shift of the optical absorption edge was observed for the transparent BaTiO3 wet gels shrinking during aging at 30 and 50°C, while no shift was observed for the wet gels aged at 5°C. The crystallinity and crystallite size of the gels increased with increasing aging time and temperature. The shift of the optical absorption edge of the BaTiO3 gels during aging was found to have a close relation to an increase in the crystallite size of the gels.
