Synthesis and features of the structure and luminescence of monodisperse SiO2/(Lu1-xEux2O3 (x=0.07) core-shell heteroparticles

Abstract : Monodisperse SiO2/Lu1.86Eu0.14O3 core-shell heteroparticles have been obtained using a method developed previously for the synthesis of spherical colloidal particles of silicon dioxide with a size spread of 2-2.5%, followed by the coprecipitation of europium-doped lutetium oxide nanocoating on these spheres. The structure of heteroparticles was studied and their photo- and cathodoluminescence spectra were analyzed. The luminescence decay time in heteroparticles is almost twice that in Lu1.86Eu0.14O3 phosphor powder prepared and treated under the same thermal conditions.
