3，5－二硝基苯甲酸对甲氧基苯乙酮加合物非线性光学晶体

Nonlinear Optical Crystal of New Organic Adduct 3,5-Dinitrobenzoic Acid p-Methoxyacetophonone

制备了具有非线性光学特性的标题加合物，采用降温法培养出２４×４５×３ｍｍ尺寸的晶形规则的单晶，同时对该加合物在乙醇中的溶解度、晶体形貌、晶体元素含量、晶体结构、红外光谱和热性能进行了测定。采用基频光１０６４ｎｍ的Ｎｄ￣（３＋）：ＹＡＧ激光辐射该晶体粉末，产生了５３２ｎｍ的倍频光。倍频光强度是ＫＤＰ的１０倍。

New organic adduct 3,5-Dinitrobenzoic acid p-Methoxyacetophonone(3,5-DNBA·pMAP)has been prepared and a large single crystal with dimensions of 24×45×3mm was obtained by slow-cooling method. The solubility curves of the 3,5-DNBA. pMAP adduct were plotted. Crystal morphology ,element content ,thermoanalysis and crystal structure of 3,5-DNBA. pMAB adduct single crystal were determined. The 3,5-DNBA. pMAP crystal powder irradiated by 1064nm Nd￣(3+):YAG Iaser beam to be produced 532nm laser. SHG intensity of crystal powder is 10 times greater than of KDP crystal powder.
