Outline of Final Research Achievements

This study aimed for developing new lead-free electro-optic (EO) materials with superior performance to lanthanum-added lead zirconate titanate (PLZT). A measuring system of EO-effect was developed for opaque polycrystalline samples prepared by conventional solid state reaction process. Materials studied were pseudo-cubic provskite relaxors. We found that some barium titanate-based relaxors with the composition of barium titanate added with barium zirconate, calcium titanate and barium tin oxide exhibited higher EO-effect than that of PLZT. The EO-coefficients showed a maximum at room temperature and decreased with increasing temperature. The temperature dependence of the EO-coefficients was similar to that of permittivity of these materials.
