摘      要：A series of rare earth complexes Tb_(1-x)Eu_x(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 Eu^(3+)increases as Tb^(3+) transfer the absorbed energy to Eu^(3+) in the complexes. The emission of Tb^(3+) 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 of Tb 3+ at 545 nm and Eu^(3+) at 614 nm are almost equal. It realizes the co-luminescence of Eu^(3+) and Tb^(3+) . We can obtain complexes with different colors by adjusting the ratio of Eu^(3+) to Tb^(3+) .
