粉末测试技术在探索新型有机倍频材料中的应用

Application of powder test to the study of new organic materials for frequency doubling

一、引 盲 Davydor(1967)等研究发现,具有以下性质的物质分子,一般都有较大的二阶极化率β:(1)电子跃迁非常大;(2)伴随着跃迁,分子偶极矩会发生显著变化。

By Kurtz's powder technique^ we have studied the SHG properties of fifty organic compounds, which include derivatives of p-ni troaniline, 2,4-dinitroaniline, p-ni troo-phenyldia-mine, diphenyl, azobenzene, diphenyl ether and diphenyl sulfide. Eight of them are found tc be promising practical nonlinear organic materials.
