Abstract

Monodisperse Pr3+/Yb3+:NaGdF4@NaYF4 active-core/inert-shell nanoparticles, which exhibit efficient near-infrared quantum-cutting luminescence, are successfully prepared. In order to relieve the adverse effect caused by concentration quenching in the core, the extra Yb3+ ions are introduced into the shell, forming an active-core/active-shell structure which leads to a much intensified near-infrared emission.
