摘要：

Effect of caesium and ceriUM, L-alanine and caeSiUM + L-alanine impurities are investigated on ferroelectric and pyroelectric properties of TGS crystals. Dielectric constant and loss, pyroelectric coefficient, spontaneous polarization and coercive field measurements of these modified crystals, as a function of temperature are reported. Caesium and cerium did not affect the electrical properties of TGS crystals significantly, whereas L-alanine- and, especially, CS + L-alanine-doped TGS crystals exhibited promising improvements in pyroelectric properties, up to 48-degrees-C, as compared to pure TGS crystals.
