摘　　要：通过对具有不同中性分子的铕和铽配合物量子效率的比较和激光化学测试,利用钆配合物做模型分子而初步得出了中性配体对铕和铽配合物发光影响的机理。中性配体的影响主要是两方面:参与分子内能量传递和影响第一激发三重态寿命。Eu and Tb complexes with different neutral ligands were synthesized and characterized. The mechanism of how the neutral ligands affect photoluminescence properties of Eu and Tb complexes was analyzed by taking the Gd complexes as model complexes. Experiments revealed neutral ligands can greatly influence the photoluminescence quantum yield and fluorescence intensity of the complexes through two main ways：taking part in the energy transfer process and affecting the triplet lifetime of the complexes.
