Article Preview

The spherical hydroxyapatite nanoparticles (HAP) were synthesized by hydro-thermal method, and calcium nitrate, terbium oxide, diammonium hydrogen phosphate were used as raw materials with the help of surfactant L-Asparagine. Meanwhile, different amount of Tb was added to investigate the effect of different terbium dropping amount on the properties of HAP. The structure, morphology and luminescent of the obtained HAP that was characterized via X-ray powder diffraction (XRD), fluorescence spectrometer (PL) and transmission electron microscope (TEM). Results showed that spherical HAP which in average of 30 nm with good dispersion showed remarkable fluorescent properties and their maximum emission were observed at 543 nm, which could be also excited at uv light region of 377 nm.The optimum mole fraction of Tb was 3%. Therefore terbium-doped spherical HAP of prepared sample would be tracked by flourescence.
