摘　　要：近些年来，溶胶－凝胶（Ｓｏｌ－Ｇｅｌ）方法作为一种软化学合成方法具有很多优点［１］，例如制作简单、烧结温度低，制得样品稳定、坚韧，制备灵活性高等。作为一种常用的染料，荧光素（ＦＬ）常用于研究非线性光学。利用Ｓｏｌ－Ｇｅｌ法可以很好地将染料分子固定在光...=\; TiO\-2 gel doped with fluorescein was prepared by a solgel method, and the fluorescence of fluorescein and its effect on formation of the gel were investigated with absorption, fluorescence, IR spectroscopies and TGDTA analysis. The results indicated that FL incorporated into TiO\-2 gel had exhibited big changes compared to that in ethanol solution both in the absorption and the emission spectra, and the formation of TiO\-2 gel was influenced greatly by FL.\;\;
