Abstract

Abstract: We have utilized a homogeneous precipitation method to fabricate core-shell Y2O3∶Er, Eu nanomaterials with colloidal mesoporous silica nanoparticles as templates followed by heat treatment at 800 ℃, and the luminescence properties of the as-synthesized nanomaterials have been investigated in detail. The core-shell nanoparticles exhibit properties of photoluminescence and near-infrared(NIR) luminescence. And Y2O3 is a promising host matrix for downconversion and NIR luminescence due to its good chemical, thermal stability and low phonon energy. The core-shell nanoparticles may have some advantages for potential applications in drug delivery or optical imaging.
