摘要：

We have synthesized a new nonlinear optical (NLO) sol-gel material. In this material, the NLO chromophores, at their ends, are covalently anchored into heavily cross-linked sol-gel networks. The poled and cured sol-gel films exhibit second-order optical nonlinearities (d(33) = 27 pm/V). Long-term stability of the nonlinearity at 100 degrees C, in air, has been realized.
