摘要： 用溶胶-凝胶法和原位加热极化聚合法制备了以4-[N,N-二-(二羟乙基)氨基苯基]-2,4-二-(4,4-二硝基苯基)咪唑(4HAPN)为生色团,以Ta(Ⅴ)的金属醇盐为无机前驱体的有机-无机杂化聚合物材料.用二次谐波产生技术和数字电荷积分法测得极化薄膜的二阶非线性光学系数d33为17.2pm/V,平均热释电系数为4.3×10-6C/(cm2·K).

关键词: 有机-无机杂化薄膜, 二阶非线性光学性能, 热释电性能

Abstract: Anovel organic and inorganic hybrid material was prepared from a nonlinear optically active imidazole derivative 4HAPN and metal alkoxide of Ta(Ⅴ) via sol-gel process. The structure of hybrids film was analyzed by FTIR and SEM, the poled film exhibits a good oriention stability analyzed by electrochromic method. The permitivity and dielectric loss were calculated from measurements made with HP4192A Impedance Analyzer. The hybrid film shows low dielectric constants and low dielectric loss. The second order nonlinear and pyroelectric properties of the hybrid film were investigated in terms of the SHG and pyroelectric coefficient measurement. The SHG coefficient, d33was found to be 17.2 pm/Vat the fundamental wavelength of 1064 nm and the pyroelectric coefficient was found to be 4.3×10-6C/(cm2·K).

Key words: Organic-inorganic hybrid thin film, Second-order nonlinear optical property, Pyroelectric property
