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；在实验上观察到由于中心离子Eu（3+）的5D2←7F0马跃迁吸收造成的配体发射光谱中的凹陷行为The luminescence properties and energy transfer of some rare earth complexes were extensively studied by laser induced fluorescence technique at room temperature. The excitation spectra of central ion ( Eu3+) was obtained. The emission spectra from the triplet state and the singlet state of ligand ( DBM) were obtained. It was found that there exists a dip peak in the emission spectra of Eu(DBM)(3).2H(2)O complex because the transition D-5(2) <-- F-7(0) of the central ion Eu3+ absorbs the emission of the ligand DBM (dibenzoylmethane).http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PAR...
