Synthesis, Characterization and Properties of Rare Earth Complexes with Caprolactam

Abstract:

Three rare earth complexes of (Eu (C₆H₁₁NO)₈, La_0.6Eu_0.4(C₆H₁₁NO)₆ , Tb_0.5Eu_0.5(C₆H₁₁NO)₆(H₂O)) were synthesized by solid-state method. The as-prepared complexes were characterized by elemental analysis, thermogravimetry-differential thermogravimetry-differential scanning calorimetry (TG-DTG-DSC), infrared (IR) spectra and fluorescence spectra. The results showed that complexed were prepared by the rare earth ions directly bonded to oxygen atoms of caprolactam ligand and emitted a characteristic fluorescence of the Eu^{3 +}or Tb³⁺ ions.
