In this study, nanostructured Ce- and Sm-substituted Ca-10(PO4)(6)(OH)(2) samples have been synthesized using an aqueous sol-gel chemistry route. For the characterization of obtained specimens, the XRD, SEM, UV-visible reflection and IR spectroscopy and luminescence measurements were recorded. It was shown that phase purity of the end products highly depends on the amount of lanthanide element. The reflectance of lanthanide-substituted calcium hydroxyapatite samples is wavelength independent in the wavelength range of 450-800 nm and equal almost 100%. The cerium-substituted samples show a significant decrease of transmission at similar to 300 nm. The characteristic samarium absorption line (similar to 430 nm) is evident in the UV-vis reflection spectra of samarium-substituted hydroxyapatites.
