Synthesis of dye-loaded NaYF4:Yb, Er superparticles for tunable upconversion emissions

Spherical superparticles consisting of small NaYF4:Yb, Er nanocrystals are developed with an emulsion method. Within each superparticle, many individual upconversion nanocrystals are condensed together and lots of small vacancies are simultaneously produced because of the packing of primary nanocrys...
