摘　　要：本文用回流冷凝法,以氧化铕、噻吩甲酰三氟丙酮为基本原料合成Eu(TTA)3phen有机发光配合物。该配合物的激发光谱为310 nm,发射光谱为612 nm。本文发现该配合物掺杂Gd^(3+)、Tb^(3+)、Y^(3+)、La^(3+)、Ho^(3+)、Sm^(3+)、Pr^(3+)稀土离子使其发光强度明显提高,其中掺杂40%Gd^(3+)离子形成的配合物发光强度最大,是Eu(TTA)3phen配合物的1.31倍。Eu（TTA）3phen luminescent complexes synthesized by Reflux condensation were prepared from the raw materials： Eu2O3, HTTA（all those are of analytical grade）. The excitation spectrum of the complex is 310 nm and the emission spectrum is 612 nm. The result indicated that Eu（TTA）3phen droped by rare earth ions（Re=Gd, Tb, Y, La, Ho, Sin, Pr） can enhance the luminescent intensity distinctly, and the luminescent intensity of 40 % Gd ions doped complex is maximum, and it is 1.31 times Eu（TTA）aphen＇s luminescent intensity.
