Sm^(3+) :TGS 晶体的生长习性、结构及铁电、热电性能

The Growth Habit, Structure and Ferroelectric-Pyroelectric Properties of Sm 3+ : TGS Crystals

选择Ｓｍ３＋为掺杂阳离子，ＤＬ丙氨酸和Ｌ－谷氨酸部分取代甘氨酸分子，生长了掺杂ＴＧＳ晶体。生长和测试实验表明，Ｓｍ３＋：ＴＧＳ晶体较纯ＴＧＳ晶体易于生长，且对称性不变，是有应用前景的热释电材料。

By choosing Sm 3+ as doping cation, and through DL-alamine and L-glulamatic acid partially substituting for glycine, several doped TGS crystals are successfully grown. The growth experiments and the measured results indicate that the growth of Sm 3+ : TGS crystals are easier than pure TGS, that the symmertry remains C 2 2 and that this series of TGS are excellent pyroelectric materials.
