Abstract

We synthesized and characterized a core-shell-shell upconverting nanoparticle architecture. Compared to the traditional core-shell architecture, we demonstrated 2-fold brighter single particle emission and 8-fold improved emission enhancement via Förster resonant energy transfer to a dye.

面向明亮上转换和改进Förster共振能量传递的核-壳-壳纳米粒子结构
我们合成并表征了核-壳-壳上转换纳米粒子结构。与传统的核壳结构相比,通过Förster共振能量转移到染料中,我们展示了2倍的单粒子发射亮度和8倍的发射增强。
