Fluorescence Enhancement of Europium(III) Perchlorate by Salicylic Acid on Phenyl-Naphthoylmethyl Sulfoxide Complex and Luminescence Mechanism

A novel ligand, phenyl-naphthoylmethyl sulfoxide, was synthesized. Its novel ternary complex and a novel binary complex had been synthesized (salicylic acid as the second ligand), and characterized by elemental analysis, molar conductivity, coordination titration analysis, FTIR and TG-DSC. The fluorescence spectra, fluorescence lifetime and phosphorescence spectra were also discussed.
