Synthesis and Fluorescence Properties of the New Binary and Ternary Complexes of Tb~(3+)、Dy~(3+)

The binary and ternary complexes of Terbium,Dysprosium were synthesized with2,4-dichlorophenoxyacetic acid as the first ligand,1,10-phenanthroline as the second ligand,By elemental analysis,EDTA complexometric titration and TG-DTG to determine the molecular formula is:RED3H2O 、RED3phen(RE = Tb,Dy;D = 2,4-Dichlorophenoxyacetic acid ion;phen =1,10-phenanthroline);Its structure was characterized by IR,UV;and the fluorescence spectra and the TG-DTG curves of the complexes were measured.The results indicated that the crystal water of RED3H2 O was lost at about140℃,and RED3 phen had better thermal stability;The binary and ternary complexes of Terbium had the property of luminescence;The influence of Y3+,Eu3+on luminescence intensity to TbD3 phen was further researched.
