摘　　要：选择荧光性能较强的稀土元素Eu为金属发光中心,β-二酮为配体,低代树形分子为掺杂剂,合成了高配位数的掺杂树形分子β-二酮配合物;并以蒙脱土为刚性体,采用插层法制得高荧光强度的稀土有机配合物/树形分子/蒙脱土纳米材料。分析结果表明,稀土有机配合物/树形分子/蒙脱土荧光材料较同类稀土有机配合物的荧光性能明显增强。In this paper, the rare earth Eu is chosen as centre of luminescence, β-diketone as ligand, low-generation PAMAM dendrimers as functional dopant, and then the high ligand β-diketone compound is prepared. Then, choosing MMT as rigid body, the rare earth organic complexes/PAMAM/MMT nanocomposite is prepared. The relation between their fluorescence intensity and the content of doped PAMAM is also discussed. The experimental results show that the PL intensity of Eu3＋ is sensitized by Hacac and PAMAM, and the fluorescence property of Eu acetylacetonate is enhanced.
