Hydrothermal Synthesis and Characterization of Tb3+ doped Hydroxyapatite

Well-dispersed nanosized Tb3+ doped hydroxyapatite (Tb-HA) powder was synthesized by hydrothermal method using poly(diallyl dimethylammonium) chloride as template. The influence the doped amount of Tb3+ on the fluorescence performance of the samples were discussed. The results show that the hydroxyapatite become luminescent by the appropriate reaction conditions. The Tb3+ ions prefer to occupy the sites Ca(II) in hydroxyapatite crystal. With the increase of Tb3+ concentration, the luminescence intensity of Tb-HA reached a maximum at the content of 4 mol%.
