| 摘要: 以BCPD为配体，按不同摩尔比掺杂Ln 3+ (Ln = Gd，Y）的Eu混合物为中心体，合成掺杂钆、钇的稀土铕配合物EuxLn1-x-BCPD，并对配合物进行了光谱分析。红外分析结果表明掺杂钆、钇后的配合物结构与未掺杂的BCPD-Eu配合物的配位结构基本保持一致；荧光分析结果表明：两种掺杂离子对铕配合物的特征荧光均存在“共发光效应”，但钆的共荧光作用要强于钇；随着掺杂离子的加入，体系中R值均大于1，且当掺杂稀土离子与铕离子的比例接近1:1时，所得掺杂配合物的荧光强度最大。实验结果为进一步开发成本低且发光性能良好的稀土发光材料提供了依据。 |

| Abstract: A series of doped Eu(III) complexes by Gd(III) or Y(III) with N,N′-bis(2-carboxyl -phenyl)-2,6-Pyridinedicarboxamide (BCPD) were synthesized and characterized by IR and fluorescence spectrum. The infrared spectra showed that the structures of the complexes doped by Gd(III) or Y(III) was the same with non-doped Eu-BCPD complexes. The solid fluorescence spectra showed that doping Gd(III) Y(III) into the Eu(III) complexes could enhance their fluorescence intensity. The luminescence intensity increased more for the Gd(III) doped complexes than the Y(III) doped complexes. The optimized fluorescence intensity of doped complexes by Gd(III) or Y(III) was at the molar ratio of Gd(III) [or Y(III)] : Eu(III) = 1∶1. The results provided clue for investigating novel rare luminescence materials. |
