| 摘 要： | 用对-苯二甲酸铵和邻菲罗啉与氯化铕和氯化镧在乙醇-水溶液中反应，合成了对-苯二甲酸邻菲罗啉铕镧异核稀土配合物，测定了配合物的C，H，N和稀土元素的含量、红外光谱、紫外光谱及荧光光谱，确定了配合物的组成。结果表明，羧基氧和邻菲罗啉氮原子均与稀土离子配位，桥联配体对-苯二甲酸根可有效的传送能量，不发光的镧离子对铕离子的发光有明显的增强作用。

| Abstract: | A series of Eu 3 (La 3 ) complexes of phen and p phthalic acid were synthesized respectively. Their IR absorption spectra, UV absorption and fluorescence spectra were studied. The results show that the oxygen atoms from p phthalic acid and nitrogen atoms from phen coordinate to the rare earth ions in the complexes. The fluorescence emission of Eu 3 ion can be greatly enhanced, if some of the europium ions in the complexes were substituted by lanthanum ions. |
