摘　　要：合成了铈(Ce)-噻吩甲酰三氟丙酮(HTTA)-邻菲口罗啉(Phen)配合物,利用荧光光谱和红外光谱研究了稀土元素镧对铈发光中心的荧光增强作用,镧的加入,使配合物发射峰的强度远远大于纯铈配合物的发射峰的强度。研究了镧的摩尔掺杂量与发光性能关系,即:1∶7>1∶1>1∶5>1∶9>1∶3,由此可见,配合物的发光强度与Ce3+的摩尔浓度不成线性关系,其中x(Ce)∶x(La)=1∶7时发光强度最好。A complex of Eu- thienyltrifluoroac etone- 1,10- phenanthroline has been synthesized. The fluorescence increment effects of La^3 ＋ have been discussed by fluorescence spectra and FT - IR spectra enlisting under the lanthanum made intencity of complax eminion greatly higher than that of pure cerium complex. The relation-ship between the adulterate quantity and luminescence performance viz ： 1 ： 7 〉 1 ： 1 〉 1 ： 5 〉 1 ： 9 〉 1 ： 3, Which shows luminence intensity of complex did not have a linear relation with the molear concentration of Ca^3＋ , the luminence intensity is the best when the proportion of Ce and Ha is 1：7.
