摘要
本文报道了有机非线性光学晶体N-(4-硝基苯基)-(L)-脯氨醇(NPP)在几种有机溶剂中的生长,在丙酮和四氢呋喃的溶剂中已分别生长出12×10×8mm ̄3以上光学质量的单晶体。通过研究晶体的生长形貌和用原子力显微镜(AFM)观察(001)面和(101)解理面的结构,并结合晶体结构阐述了NPP分子和晶体所具有的结构特征,以及这些结构特征对晶体形貌和生长习性所产生的影响。
In this paper,the growth of N-(4-nitrophentyl)-(L)-prolinol (NPP)crystal in several kinds of organic solvents were studied ,larger perfect single crystals havebeen obtained from acetone by evaperation and from tetrahydrofuran(THF)bylower-temperature method,respectively.The crystal morphology and themechanism of growth were analyzed according to the investigation on micros-radi-cals and crystal structure by using polarizing microscopy and atomic force mi-croscopy(AFM),the relations between the growth habits and structural propertieswere discussed.
