Zinc-substituted hydroxyapatite was successfully synthesized by a simple hydrothermal method. This kind of Zn-substituted hydroxyapatite is environmental friendly phosphor material which has excellent photoluminescence (PL) property without containing toxic substance or expensive rare earth elements. The products were characterized via X-ray diffraction (XRD), Fourier transform infrared (FT-IR), photoluminescence (PL) excitation and emission spectra and kinetic decay curve. The PL intensity of Zn-substituted hydroxyapatite with different Zn content was investigated in detail. The photoluminescence intensities (PL) can be tuned by altering the doping concentration of Zinc. The possible luminescent mechanism of the PL intensity of the Zn-substituted hydroxyapatite was discussed.
