Article Description

The complexes RE(Phe) 3 PhenCl 3 ·3H 2 O (Phe: phenylalanine; Phen: o -phenanthroline; RE: La 3+, Y 3+ and Eu 3+ ), RE 0.2 Eu 0.8 (Phe) 3 PhenCl 3 ·3H 2 O (RE: La 3+ and Y 3+ ) were synthesized and characterized in detail. IR spectra and Raman spectra indicated that the rare earth ions are coordinated by both the oxygen atom from the COO − group and the nitrogen atom from o -phenanthroline. The RE 0.2 Eu 0.8 (Phe) 3 PhenCl 3 ·3H 2 O also displayed co-fluorescence effect. The antibacterial activities testing showed that all these complexes exhibited excellent antibacterial ability against Escherichia coli, Staphylococcus aureus and Candida albicans.
