摘 要:Eu 3+ ions were incorporated in sol and gel by a sol gel processing using 3 glycidoxypropyltrimethoxysilane (CH 2OCHCH 2O(CH 2) 3Si(OCH 3) 3, GPTMS) and ethyl silicate (TEOS) as precursors. The basic chemical physical properties such as DTA curve, FT IR spectra and specific surface area were recorded. The characteristics of their optical spectra were measured and investigated. The results indicate that the emission intensity of Eu 3+ ion in ormocer is much higher and the global line width is wider than those in SiO 2 gel. The relationship between the composition and structure of gels and the fluorescence intensity and width were discussed. The obtained ormocer shows good mechanical strength, which can be cut and polished in machine without broken.Eu 3+ ions were incorporated in sol and gel by a sol gel processing using 3 glycidoxypropyltrimethoxysilane (CH 2OCHCH 2O(CH 2) 3Si(OCH 3) 3, GPTMS) and ethyl silicate (TEOS) as precursors.
