摘　　要：合成了标题化合物,并用红外光谱、紫外光谱、元素分析和热重-差热分析及荧光光谱对配合物进行了组成确定和表征。荧光分析结果表明配体能够激发Eu3+的电偶极跃迁而发红光,配合物具有很好的荧光性能,是一种潜在的红色发光材料。A new β-diketone rare earth europium complex （2-isovaleryl- 1,3-indandione-Eu ） was synthesized. The properties of this complex were characterized by elemental analyses, IR, UVVisible spectrometry and TG-DSC. The fluorescence spectra showed that the ligand could stimulate＇Eu^3＋ electron dipole transition and emit red light. The results showed that the complex had excellent fluorescent property and could be a kind of potential red luminescent material.
