Abstract

We report for the first time the synthesis of monodisperse, magnetic and up-conversion luminescent Fe₃O₄@NaGdF₄:Yb/Er@NaGdF₄:Yb/Er core–shell structured nanoparticles (NPs) by a seed-growth process. The growth of a NaGdF₄:Yb/Er shell on Fe₃O₄@NaGdF₄:Yb/Er NPs can significantly enhance the up-conversion emission intensity.
