用溶胶-凝胶法在电场作用下制备了含4-(二甲氨基)-4/-亚硝基(DANS)和4-(2-(4-羟基苯基)乙烯基)-N-甲基吡啶(HAMP)碘化物的T1O2光学非线性薄膜。T1O2/DANS的二阶非线性约为11 pm/V，随着薄膜中分子取向的松弛，二阶非线性在数月内衰减。当用硅烷锚链修饰碘化大麻时，下降速度明显变慢。
Optically nonlinear T1O2 films containing 4-(dimethylamino)-4/-nitrostilbene (DANS) and 4-(2-(4-hydroxyphenyl) ethenyl)-N-methylpyridinium (HEMP) iodide were prepared by the sol-gel process under an electric field. The second-order nonlinearity was about 11 pm/V for T1O2/DANS, and it decayed in months by the relaxation of molecular orientation in the film. When HEMP iodide was modified with a silane anchor, thedeclination became significantly slow.
