摘要

Luminescence spectra and lifetime of Eu(III) andTb(III) ions in complexes with glycine (AAA), glycolic acid (GA),aspartic acid (ASP) and manic acid (MA) were studied. The effectof the amino-NH_2 and hydroxyl-OH groups on the intensity andlifetime of the lanthanides luminescence were examined.Hydration number for Eu(III) in the systems studied indicated theinvolvement of carboxyl and hydroxyl groups as well as donornitrogen atoms in the coordination. The phenomenon of Gd(III)ion emission quenching was analyzed and quantitatively describedby determination of the quenching constant K_(SV).
