摘 要:本文主要是研究以2,6-二羧基-4-(4-苯甲酸)吡啶(CBDPA)为配体,合成含Eu3+的稀土配合物即Eu(CBDPA)3 。然后将稀土配合物Eu(CBDPA)3与粘土进行复合形成发光复合材料。分别采用红外光谱、紫外可见光光谱、荧光光谱、X-射线衍射等分析仪器,对稀土配合物复合材料的荧光性质行了研究、分析和对比。研究了配体和复合材料的制备及其对稀土配合物复合材料在荧光性质的影响。36214 毕业论文关键词:稀土铕;配合物;配体;荧光性能;发光复合材料
Study on the synthesis and properties of rare earth complexes based on composite materials
Abstract: In this paper, we mainly study to 2, 6 - carboxyl - 4 - (4 - benzoic acid) pyridine CBDPA as ligand, synthetic containing rare earth Eu3 + complexes Eu (CBDPA) 3.Then the rare earth complexes with claycomposite forming luminescent composites. Respectively by infrared spectroscopy, ultraviolet visible light spectra, fluorescence spectroscopy, X-ray diffraction analysis instrument, of rare earth with the fluorescent properties of composites was studied, analyzed and compared. Study of the ligand and the preparation of composite material and its effect oncomplexes of rare earth composite materials in fluorescence properties.
Keywords: Rare earth Eu;The complexes;The ligand;Fluorescence property ;Light composite materials
