Sub-10 nm [small beta]-Na(Y,Gd)F₄:Ce,Tb,Eu/[small beta]-NaYF₄ core/shell nanocrystals show highly bright and multicolor emission under a single wavelength excitation via energy transfer of Ce³⁺ [rightward arrow] Gd³⁺ [rightward arrow] Tb³⁺ [rightward arrow] Eu³⁺ and the nanoparticle-polymer composites show high transparency and multicolor tunability.
