【Abstract】 The rare earth complex compounds of Tb 3+ with o aminobenzoic acid doped with Ln 3+ (La 3+ , Gd 3+ ,Y 3+ ) have been synthesized. The fluorescence properties of the compounds are studied, the experiment result shows that the fluorescence of Tb 3+ complex are enhanced greatly after doping with La 3+ , Gd 3+ ,Y 3+ .The influence of doping ions and doping content on the fluorescence have been investigated.The substitution of most Ln 3+ for Tb 3+ is obtained with satisfaction enhancing luminescence.更多还原
