A series of rare earth complexes Tb1-xEux(MAA)3phen (x=0.00,0.01,0,03,0.05,0.07,0.09,0.10,0.30,and 0.50) were synthesized with MAA as the first ligand and phen as the second ligand.The complexes were characterized by means of FT-IR,thermogravimetry-differential scanning calorimetry (TG-DSC),XRD,UV absorption spectra,and photoluminescence spectra (PL).The results show that the luminescence intensity of Eu3+ increases as Tb3+ transfer the absorbed energy to Eu3+ in the complexes.The emission of Tb3+ at 545 nm is observed and increasing with x decreasing.When x=0.01,the luminescence intensity reaches the maximum value,and the emission intensity ofTb3+ at 545 nm and Eu3+ at 614 nm are almost equal.It realizes the co-luminescence ofEu3+ and Tb3+.We can obtain complexes with different colors by adjusting the ratio of Eu3+ to Tb3+.
