The fluorapatite (FAP) nanoparticles doped with rear earth elements have been extensively studied as a potential luminescence inorganic material for in-vitro and in vivo cells and tissue bioimaging [1-3]. Luminescent nanoparticles of undoped and Pr3+ doped fluorapatite (Pr-FAP) have been successfully synthesized by co-precipitation method followed by calcination. Obtained materials are characterized by XRD, FTIR FAR, PLE-PL and SEM-EDAX methods, and theoretical prediction of structural changes was also done.
Emission of FAP nanoparticles occurs in violet-blue region of visible part of
spectrum under excitation in UV region. Introducing the Pr3+ into the lattice causes the red or blue shift depending of Pr3+ concentration and synthesis conditions. MCR-ALS analyses of fluorescence spectra and ab initio calculation indicated that Pr3+ ions are located in Pr-FAP lattice at Ca2 (6h) sites. Assumed mechanism of substitution of Ca2+ with Pr3+ ion is accompanied with charge compensation by ...incorporation of CO32- ions into the structure or by vacancies formation on metal ions position. Synthesized nanoparticles can be potentially used as a luminescent nanomaterials in biomedicine for targeting, bioimaging, drug delivery and therapy.
