Synthesis and Photoluminescent Properties of Eu2+-Doped BaSiF6 Nanoparticles

By adjusting the molar ratio of oleic acid (OA), oleylamine (OM), and 1-octadecene (OD) ligands in reaction solution, Eu2+-doped BaSiF6 nanoparticles were synthesized using a thermal decomposition synthesis route. Eu2+ ions have been successfully doped into BaSiF6 host lattice and strong 4f–4f line emission of the Eu2+ in BaSiF6 matrix is observed. Meanwhile, the photoluminescent (PL) properties of BaSiF6:Eu2+ nanoparticles doping Eu2+ ions at different concentrations were also studied.
