Study of the luminescence properties of a novel rare earth complex Tb(DPC)(2)2H2O.

Rare earth complex Tb(DPC)(2)2H(2)O was synthesized by introducing Pyridine-2,6-dicarboxylic acid(H(2)DPC) as the ligand and characterized by UV, fluorescent and infrared spectra as well as elemental analysis. The complex exhibited ligand-sensitized green emission, and it has the higher sensitized luminescent efficiency and longer lifetime. The effect and mechanism of the ligand (H(2)DPC) on the luminescence properties of terbium complex was discussed.
