A concise route to prepare water-soluble rare-earth ion doped upconversion nanoparticles (UCNPs) by encapsulation of grafted cationic conjugated polyelectrolyte brushes (PFNBr) is reported. Integrating two kinds of upconversion materials effectively addresses multicolor fluorescence by introducing the concept of dual-upconversion.
本文报道了一种通过接枝阳离子共轭聚合物刷（PFNBr）封装来制备水溶性稀土离子掺杂上转换纳米粒子（UCNPs）的简洁路线。通过引入双上转换的概念，有效地整合了两种上转换材料，实现了多色荧光。
