| Abstract: | The emission spectra and their lifetimes of the complexes of Eu(Ⅲ) and Tb(Ⅲ) with mixed β-diketone and organic ligands were studied by laser induced fiuorescence technique. The energy levels of the centered metal ions were less affected by different ligands (less than 100cm-1), but the lifetimes and the emission intensities of the ions depends on the efficiency of the energy transfer between the ligand and the ions. The energy levels split in strong ligand fields. The emission spectra of Eu(Ⅲ) complexes gave a set of energy constants of the 7F and 5D states of Eu(Ⅲ) as following: for 7F: A=305cm-1, B0=3660cm-1; for 5D: A=1744cm-1, B=27699cm-1. |
