Preparation and Characteristics of Organical Modified Silicates Xerogel for Optical Applications
有机改性光功能固态凝胶基质材料的制备与性能研究

The sol-gel processing of acid-catalyzed tetrasthoxysilane or tetrabutoxytitanate and MMA (monomeric methyl methacrylate), GPTMS(3-glycidyl propyl trimethoxisilane) to produce laser dye Rhodamine B doped silica and titania organical modified sol-gel materials was systematically studied. Pseudo--ternary phase diagram was used to outline the regions of stability of the solgel system on certain conditions. IR, TG/DTA, absorption and emission spectra were used to analyse the thermal, machnical, optical properties of the sol-gel materials. It was found that TiO2 -Ormosils exhibited good thermal stability, mechanical and optical properties.
