一种新型稀土光能转换材料的合成及应用

合成了一种新型的多支化苯甲酸配体,并且以该配体作为第一配体,1,10-邻菲罗琳作为第二配体、Eu3+离子作为发光中心,合成了多支化稀土光能转换材料.通过IR、元素分析、DSC、TG和荧光光谱对有机稀土光能转换材料的结构以及热性能和荧光性能进行了研究.红外光谱表明配体和phen与稀土Eu3+进行了配位.荧光光谱表明该稀土光能转换材料具有优异的荧光性能.

Synthesis and Application of a Novel Rare Earth Optical Conversion Material

We design and synthesize a novel multi-branched benzoic acid ligand. The composition and structure of the ligand was char-acterized by IR, 1HNMR spectra. A novel rare earth complex was synthesized through Eu3+ as a luminescent center, multi-branched benzoic acid ligand as the first ligand, phen as the second ligand. The composition and structure of the rare earth complex were charac-terized by IR, elemental analysis. IR shows that the ligand has coordinated with rare earth Eu3+ through carboxyl oxygen. Fluorescence spectra show that the rare earth complexes have excellent luminescent property.
