以苯乙酮酸（HL）和红菲绕啉（Bath）为配体，合成了两种Eu（Ⅲ）配合物。采用元素分析、等离子体原子发射光谱（ICP）、FT-IR和1 H NMR对配合物的组成及结构进行了表征。研究了两种配合物的热稳定性和荧光性能（激发光谱、发射光谱、荧光寿命和量子产率）。结果表明：两种配合物的分子式分别为EuL3·xH2 O和EuL3 Bath。当引入第二配体Bath，配合物的起始分解温度由219℃（EuL3·xH2O）提高到了293℃（EuL3Bath），改善了配合物的热稳定性；同时，配合物荧光性能显著增强，主要表现在荧光发射强度明显增强，量子产率提高了9.02%，荧光寿命延长了3.01 ms。

Two Eu(Ⅲ)complexes were synthesized with phenylglyoxylic acid( HL)and bathophenanth-roline( Bath). Their chemical compositions and structures were characterized by means of elemental anal-ysis,inductively coupled plasma atomic emission spectrometer( ICP),FT-IR and 1 H NMR. The ther-malstability and fluorescence properties( excitation spectra,emission spectra,fluorescence lifetime and quantum yield)were studied. The results show that the molecular formulas of complexes are respectively EuL3 ·xH2 O and EuL3 Bath. When the second ligand Bath introduces,the initial thermal decomposition temperature of complexes increase from 219 ℃ for EuL3 ·xH2 O to 293 ℃ for EuL3 Bath,which improved thermalstability of Eu(Ⅲ)complexes. At the same time,the fluorescence properties of complexes were significantly enhanced. Fluorescence emission of Eu(Ⅲ)complexes remarkably strengthened. Quantum yield increased by 9. 02%. Fluorescence lifetime prolonged by 3. 01 ms.
