摘要：
The complexes RE(Phe)(3)PhenCl(3)(.)3H(2)O (Phe: phenylalanine; Phen: o-phenanthroline; RE: La3+, Y3+ and Eu3+), RE0.2Eu0.8(Phe)(3)PhenCl(3)(.)3-H2O (RE: La3+ and Y3+) 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 RE0.2Eu0.8(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.
