摘要：
A series of lanthanide metal complexes [Ln = Sm (1 and 5), Eu (2 and 6), Tb (3 and 7), Er (4 and 8)] were synthesized with imidazole- containing beta-diketone ligands. Complexes 1-8 were characterized by IR, elemental analysis, powder XRD, and TG measurements. The photoluminescence properties and the probable mechanism of the Sm, Eu, and Tb complexes were studied. The Eu complex generated strong red light in response to excitation with purple light (380420 nm). Their fluorescence lifetime of 2 and 6 were 378 and 267 mu s, respectively. The measurement and analysis of the thermal properties showed that these were thermal stable. Therefore, it can be applied to LED fluorescent powder.
