Synthesis and Fluorescent Properties of Rare Earth Ternary Complexes with Salicylic Acid and 1,10-phenanthroline

Li Song

Abstract

Three ternary complexes of RE3+ ions(RE=Eu,Tb,Tb/Ce) were synthesized with salicylic acid(H2sal) and 1,10-phenanthroline(phen) ligands.The compositions of the complexes were determined by the EDTA rare earth complexometric titration analysis and C,H,N element analysis.The infrared(IR) spectra of ligands and complexes were measured and the fluorescent properties of the complexes in solution were studied in detail.
