核/壳结构的二氧化硅/NaYF 4纳米球具有均匀的二氧化硅涂层,使用一个简单的,用户友好的方法合成。通过将有机染料或量子点封装在二氧化硅壳中来产生多色纳米球,并且基于荧光共振能量转移(FRET)来产生上转换荧光。
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).
