溶胶－凝胶技术是制备材料的一种新兴低温工艺，它为两种完全不相容的成份—聚合物材料和无机玻璃的大比例混合（或键合）创造了可能，使得制备出的材料兼备两种成份的优点。本文综述了近年来溶胶－凝胶技术在制备有机／无机复合非线性光学材料领域中的应用，并简要分析了当前研究工作所面临的问题。 Sol-Gel technology is an emerging low-temperature process for the preparation of materials that makes it possible to mix (or bond) large proportions of two completely incompatible components, polymeric materials and inorganic glasses, so that the prepared material Both the advantages of both ingredients. This review summarizes the application of sol-gel technology in the preparation of organic / inorganic composite nonlinear optical materials in recent years, and briefly analyzes the problems in the current research work.
