A series of [(nC4H9)4N][EuxM1－x (TTA)4](M=La, Sm,Gd, Tb) dopedcomplexes were synthesized. The results of FTIR and XRD spectroscopies indicated that the structures of the doped complexes are as same as that of pure complexes [(nC4H9)4N][Ln(TTA)4](Ln=Eu, La, Sm, Gd, Tb). It is found that the luminescent intensity of the dopedcomplexes did not have a linear relation with amount of Eu3＋. Addition of La3＋, Gd3＋ and Tb3＋ increased the luminescence of Eu3＋ in varying degrees, and addition of Sm3＋ decreased the luminescence of Eu3＋. The possible intermolecular energy transfer mechanism by triplet states of ligands was discussed.
