Sol-Gel法制备有机-无机复合光致变色膜

Manufacture of Inorganic Organic Composite Photochromic Films by Sol Gel Process

本文讨论了用ｓｏｌｇｅｌ法在有机改性ＳｉＯ２基体中于室温下俘陷有机染料如螺吡喃或螺口恶嗪，制备出具有光致变色功能的有机无机复合膜。该膜层在可见光区的最大吸收峰位于６２０ｍｎ处。

Inorganic organic composite thin films with the function of photochromism based on room temperature trapping of organic dyes such as spiropyranes or spirooxazines in modified silicon oxide matrices by sol gel process are discussed. The maximum absorbtion density of the films in the visible light area is at 620nm.
