摘要：
A new europium complex containing the chelate tridentate ligand and imidazole terpyridine (itpy), was synthesized. The complex was characterized by elemental analysis, mass, FT-IR and photoluminescence spectroscopic techniques. The europium complex in solution showed characteristic luminescence properties. The room temperature photoluminescence spectrum of this complex was composed of typical Eu3+ red emission assigned to D-5(0) -> F-7(2) transition. The metal-centered red emission seemed to be promoted by the ligand-assisted energy transfer, namely antenna effect.
