| 摘 要： | Fluorescence and cofluorescence properties of Tb(Ⅲ) solid complexes were studied using pyromellific acid (PMA) as ligand and fluorescence inert ions as doping elements. The cofluorescence enhancement, a result of ligand sensi-tized fluorescence, was observed in Th(Ⅲ) solid complexes doped with fluorescent inert ions La(Ⅲ), Gd(Ⅲ), Ca(Ⅲ), and Sr(Ⅲ). The effect of the type and content of doping elements on fluorescence enhancement was studied, and optimum con-ditions were determined. The results show that Gd (La, Ca, Sr) has clear cofluorescence effect in solid complex Tb-M-PMA system, and in present work, rare earth complex fluorescent powder that emits bright green fluorescence at ultraviolet exci-tation was obtained, which had potential application as fluorescent anti-counterfeit ink,
