摘要：
系统地提出了复杂晶体化学键的介电理论方法,计算了一些非线性晶体的二阶极化系数dij。计算结果和实验值符合很好,同时表明这种方法不仅可应用于复杂晶体,还提供了材料设计的某些依据。
关键词: 复杂晶体, 化学键, 非线性光学系数dij
Abstract:
A theoretical method on constituent chemical bonds of complex crystals based on the dielectric theory of solids has been proposed systematically, the independent nonlinear optical tensor co-efficients dij of some typical NLO cxystals with complex structures have been quantitatively calculated. Theoretical values agree with experimental data satisfactorily.This work shows that our method has a good application in dealing with optical nonlinearities of complex crystals, it also would be useful in designing or modifying new NLO crystal materials.
Key words: complex crystals, chemical bond, nonlinear optical coefficient dij
