摘　　要：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＋ 离子的加入能显著的提高配合物中Ｅｕ３＋ 中心的发光强度， 这种荧光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．The advantage of luminescence of the complexes of rare earth ion and organic compounds are: high intensity of luminescence, narrow wave peak, bright color, good stable character, little decline in light, hard to be oxidized, and so on . Because of these advantages, the complexes of rare earth ion and organic compounds are widely used. The fluorescence increment effect of rare earth ion and organic compounds, such as Gd 3+ , La 3+ and Y 3+ , can enhance the luminescence intensity of the certer ion of complexes, and provides scientific basis of further research and use of luminescence of rare earth complex compounds. Synthesis of the iso polynucleus by the fluorescence increment effect has become an important subject in the field. In this paper, the iso polynucleus complexes of Eu(Ⅲ) are synthesized based on fluorescence increment effect of rare earth. The complexes are characterized by element 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 centent of Eu in the complexes and production cost. The influence of acidity on luminescence and the influence of temperature on luminescence while forming the complexes are also discussed in this paper.
