摘要: 合成了一系列吡唑啉酮类稀土铽、铕、钐、钆、镝的配合物, 并采用元素分析、红外光谱和紫外-可见光谱对其进行了表征, 解析了铕配合物的晶体结构. 测定了配体的三重态能级, 研究了这4种配合物的发光性质. 并通过研究配体到稀土离子的能量传递过程, 合理地解释了这些稀土配合物发光性质的差异.

Abstract: A series of lanthanide(Tb3+, Eu3+, Sm3+, Dy3+, Gd3+) complexes with 1,3-diphenyl-4-phenyl-acetyl-5-pyrazolone were synthesized and characterized by elementary analysis, FTIR and UV-Vis spectra. The Eu3+ complex was further characterized by X-ray diffraction. The luminance properties of the lanthanide complexes were studied in detail. Importantly, the triplet energy level of the ligand was measured with reference to the phosphorescence spectrum of its gadolinium complex, and the difference between the ligand's triplet energy level and the excited energy level of lanthanide ion results in different photoluminescences of the corresponding complex.

Key words: Lanthanide complex, Photoluminescence, 1,3-Diphenyl-4-phenylacetyl-5-pyrazolone ligand, Electroluminescence
