Tb ̄(3+) and Eu ̄(3+) complexes of N, N ', N'-1, 3, 5-triazine-2, 4, 6-triyltris-[N- (carboxymethyl)]-glycine were synthesized and characterized by elemental analysis, TG-DTA, UV,IR, fluorescence and phosphore...Tb ̄(3+) and Eu ̄(3+) complexes of N, N ', N'-1, 3, 5-triazine-2, 4, 6-triyltris-[N- (carboxymethyl)]-glycine were synthesized and characterized by elemental analysis, TG-DTA, UV,IR, fluorescence and phosphorescence spectroseopy. It was shown that the ligand can sensitize the fluorescence of Tb ̄(3+) but not sensitize the luminescence of Eu ̄(3+). The mechanism of luminescence was discussed based upon the phosphorescence of the ligand.展开更多
