摘要
报道了一组新设计的染料分子以掺杂和共聚两种形式加入基质ＰＭＭＡ聚合物．并制成固体薄膜。采用电晕极化（Ｃｏｒｏｎａ－Ｐｏｌｉｎｇ）．获得较大二阶非线性系数（ｄ３３＝１．２６×１０－７ｅｓｕ）．具有较好稳定性。详细研究了极化条件、分子结构、加入基质方式对非线性光学强度和稳定性的影响。
it is rePOrted that with some new dye molecules added to PMMA by doping and copolymerizing Prepare to solid films are Prepared. With a corona-POling method, a land stable second-order nonlinear optical coeffiCient is obtained (d33 = 1.26 × 10-7 esu).The influences of POling condition, molecular Structure and the different type films on the magnitude and stability of NLO properties are studied in detail.
