铕(Ⅲ)异多核配合物的合成及其共荧光性质

SYNTHESIS AND CO FLUERESCENCE CHARACTER OF EU(Ⅲ) ISO POLYNUCEAR COMPLEXES

利用荧光增强效应合成了铕（Ⅲ）异多核固体配合物，通过元素分析、等离子体发射光谱、红外光谱、荧光光谱等测试手段研究了配合物的组成、结构和发光性质．结果表明增强离子Ｇｄ３＋、Ｌａ３＋和Ｙ３＋的加入能显著的提高配合物中中心离子Ｅｕ３＋的发光强度，这种荧光增强效应能减少较为昂贵的铕在配合物中的用量，从而降低产品的成本．

Iso polynucear complexes of Eu(Ⅲ) are synthesised based on co fluorescence effect of rare earth. The complexes are characterized by elemental analysis, plasma spectra, IR spectra and fluorescence spectra. It has been confirmed that the addition of Gd 3+ 、La 3+ and Y 3+ can give a great improvement on the fluorescence intensity of center Eu 3+ in the complexes and it was reduced that the content of Eu in the complexes and production cost.
