摘　　要：利用激光诱导荧光技术研究了稀土铕等金属配合物的发光特性及其能量传递动力学过程．得到了这些稀土配合物中中心离子Eu（3+）的激发光谱，配体的三线态发时光谱和单线态发射光谱；The lunmescence properties and energy transter of some rare earth complexes wereextensively studied by laser induced fluorescence technique at room temperature. The excitationspectra of central ion (Eu3+ ) was obtained. The entission spectra from the triplet state and thesinglet state of ligand (DBM ) were obtained. It was found that there exists a dip peak in theennssion spectra of Eu(DBM )3.2H2O complex because the transition 5D3 -7F0 of the central ionEu3+ absorbs the emission of the ligalld DBM (dibenzoylmethane).
