Abstract
The complexes Ln(Asn)3PhenCl3.3H2O (Asn: asparagine; Phen: o-phenanthroline; Ln: Er,Tm), have been synthesized and characterized studies based on thermal. IR spetra indicatedthat the rare earth ions are coordinated by both the oxygen atom from the COO- group andthe nitrogen atom from the NH3+ group from asparagine and the nitrogen atom from ophenanthroline.The complexes were also compared in terms of fluorescent properties.
