摘要：

Core/shell-structured silica/NaYF4 nanospheres featuring uniform silica coatings are synthesized using a facile, user-friendly method. Multicolor nanospheres are produced by encapsulation of organic dyes or quantum dots in the silica shell, and upconversion fluorescence is generated based on fluorescence resonance energy transfer (FRET).
