摘要：

New-style fluorescent material of SiO2/Eu(TTA)(3)phen was synthesized by the mothed of dispersing Eu(TTA)(3)phen in isopropanol and hydrolyzing TEOS. Fluorescence spectra showed that the emission intensities of SiO2/Eu(TTA)(3)phen were much more stronger than that of Eu(TTA)(3)phen by more than two times. At the same time, the peak at 617. 4 nm became very sharp, which could not be observed for Eu(TTA)(3)phen. This indicated that the structure of Eu(TTA)(3)phen became more rigid after coated by SiO2. Thus, the emission intensity was enhanced largely. Life-time of SiO2/Eu(TTA)(3)phen decreasing just confirmed the rigidity of SiO2/Eu(TTA)(3)phen.
