Four ternary complexes [Ln2(PIA)2(acac)2] (Ln=Sm (1), Eu (2), Tb (3), Dy (4)) were synthesized with isophthalic acid (H2PIA, C8H6O4), acetylacetone(Hacac, C5H8O2) and Ln(NO3)3·nH2O in ethanol solution. These complexes were characterized by elemental analysis, infrared (IR) spectra, and thermogravimetric analysis (TG). Their possible structures were proposed. In order to compare the luminescent properties between ternary complexes and corresponding binary complexes, the binary complexes [Ln2(PIA)3(H2O)4] and Ln(acac)3(H2O) (Ln=Sm, Eu, Tb, Dy) were also prepared. The fluorescent spectra of the ternary and binary complexes were determined at room temperature. The results show that all complexes displayed the characteristic emissions of rare earth center ions. The luminescent intensities of the ternary complexes (except the dysprosium complex) were stronger than that of the binary complexes, indicating that the synergistic sensitization effect had occurred for the center ions from the double ligands. These experimental results can be explained by the energy matching of the lowest triplet energy level T1 of the two ligands (calculated from Gaussian theory) and the lowest excited state energy level of the central metal ions.
