Preparation and characterization of Eu3+-doped fluorapatite nanoparticles by a hydrothermal method
Source abstract
Abstract
Abstract In this study, luminescent Eu 3+ -doped fluorapatite (Eu 3+ :FA) was successfully synthesized by a hydrothermal process by using Na 2 EDTA/citric acid (CA) as the chelating agent. X-ray diffraction (XRD), transmission electron microscopy (TEM) and photoluminescence spectra (PL) were utilized to characterize the obtained nanoparticles. The results showed that Eu 3+ ions entered the FA lattice and occupied Ca 2+ sites, which resulted in a decrease in the values of the lattice parameters. The as-prepared luminescent samples exhibit sphere-like aggregates that are constructed of small nanospheres and that are well dispersed with a good size distribution. Upon excitation by UV radiation, the Eu 3+ :FA samples demonstrate the characteristic 5 D 0 – 7 F 1–2 emission lines of Eu 3+ . Finally, the influence of Na 2 EDTA/CA on the morphology of Eu 3+ :FA nanopowder was also discussed.
