Abstract：New-style fluorescent material of SiO2/Eu(TTA)3phen was synthesized by the mothed of dispersing Eu(TTA)3phen in isopropanol and hydrolyzing TEOS. Fluorescence spectra showed that the emission intensities of SiO2/Eu(TTA)3phen were much more stronger than that of Eu(TTA)3phen 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)3phen. This indicated that the structure of Eu(TTA)3phen became more rigid after coated by SiO2. Thus, the emission intensity was enhanced largely. Life-time of SiO2/Eu(TTA)3phen decreasing just confirmed the rigidity of SiO2/Eu(TTA)3phen.
