Abstract:

 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 excitation 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 )3.2H2O complex because the transition 5D3 -7F0 of the central ionEu3+ absorbs the emission of the ligand DBM (dibenzoylmethane).

Key words: Rare-earth(III) complex, Laser induced fluorescence, Energy transfer
