摘要

The binary solid complexes had been synthesized using rare-earth ion with p-nitrophenylacetic acid. The chemical formula of ReL3.H2O(Re = Eu, Sm, Tb) complexes was determined by elemental analysis, molar conductivity, and TG-DTA. The composition structure and properties of the binary complexes were tentatively investigated by the analysis of IR, UV, and fluorescence spectra. The IR showed the carboxylic ligand chelates to the center ion to form the complexes, and the complexes contain water molecule of hydration. The result above was also proved by comparison of UV of the ligand and complexes. Two bands of strong red fluorescence of ReL3.H2O may be contributed to the fluorescence spectra of 5D0-->7 F1 and 5D0-->7 F2 transition of Eu3+.
