摘要：

Cerium(IV)- and bismuth(III)-substituted hydroxyapatite nanoparticles were synthesized by the co-precipitation method from aqueous solutions of various Ce/(Ce+Ca) = X-ce or Bi/(Bi+Ca) = X-Bi atomic ratios ranging from 0 to 0.5. Samples were characterised by scanning electron microscopy (SEM)(Bi) coupled with X-ray analysis (EDX), X-ray powder diffraction (XRD) and fluorescence spectroscopy. The luminescence characteristics of the CO4+ and Bi3+ ions in the hydroxyapatite lattice have been studied under the e(exc) = 300 nm. The results obtained from the fluorescence spectra revealed that the optical properties of the hydroxyapatite samples are modified by the substitution with cerium or bismuth ions.
