摘 要：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 of Tb 3+ at 545 nm and Eu3+ at 614 nm are almost equal. It realizes the co-luminescence of Eu3+ and Tb3+ . We can obtain complexes with different colors by adjusting the ratio of Eu3+ to Tb3+ .
