摘 要：Rare earth （RE） ternary complexes of Eu0.5Ln0.5（NPPD）3·（DPQ） （HNPPD=1-（naphthalen-2-yl）-3-phenylpropane-1,3-dione; DPQ= dipyridobenzoquinone） and Eu1-xLax（NPPD）3·（DPQ） （Ln3+=La3+, Gd3+, Sm3+, Pr3+; x=0.0, 0.1, 0.3, 0.5, 0.7, 0.9） were synthesized by the reaction of RECl3·6H2O with HNPPD and DPQ in stoichiometry. The complexes were characterized with IR, elemental analysis, TGA-DSC and wide-angle X-ray diffraction. The UV-Vis absorption spectra and fluorescence properties of the complexes were also investigated. The experimental results showed that the luminescence efficiency of Eu3+ complexes was enhanced by doping some other lanthanide ions. Eu0.7La0.3（NPPD）3·（DPQ） showed the highest luminescence efficiency.
