英文摘要	Methyl methacrylate (MMA) and ethyl methacrylate (EMA) doped with luminescent ternary europium complex (Tb(acac)(3)-phen) with acetylacetone (Hacac) and 1,10-phenanthroline (phen) is incorporated into microporous silica gel, and the polymerization of MMA (and EMA), hybrid material containing Tb(acac)(3).phen has been obtained. The material exhibits good toughness and transparency. The TG-DTA curves have been determined, indicating that the hybrid matrix exhibits more thermal stability than that of the pure complex and pure polymer matrix. The luminescence spectra of all hybrid material doped with Tb(acac)(3).phen show the characteristic excitation and emission of europium ions and there. exists some slight shift of maximum wavelength (about 3 8 0 nm), which implies the same energy transfer mechanism as the pure complex, and the hybrid matrix is a suitable substrate for the luminescence of europium ions. In the range of doping concentration of Tb(acac)(3).phen (0.65, 0.1, 0.2, 0.5, 1.0, 2.0 and 5.0 wt.%), emission intensities increase with the increasing of corresponding doping concentration and concentration quenching effect has not taken place. The emission spectra of terbium complex have been intensified by incorporating it into the hybrid matrix, and the specific emission intensities per complex formula unit is increased, compared with that of original complex.
