Highly aqueous soluble CaF2:Yb/Er@CaF2@SiO2 upconversion nanoparticles were prepared via metal complex decomposition rout. Gradually surface coating with an inert CaF2 and silica layers greatly enhanced their optical and luminescence properties, which are highly usable for luminescent biolabeling or optical bio-probe etc.
