Water dispersible upconverting polyethylenimine (PEI)-capped NaYF(4) nanoparticles co-doped with trivalent erbium (Er(3+)) and ytterbium (Yb(3+)) were prepared via solvothermal synthesis with an 18 nm average particle diameter. These upconverting nanoparticles can be used to sensitize a light-harvesting phycobiliprotein (R-Phycoerythrin) via luminescence resonance energy transfer (LRET).
水相分散的聚乙二烯亚胺（PEI）包覆的 NaYF(4) 纳米粒子共掺杂三价铒（Er(3+)) 和镱（Yb(3+)) 通过溶剂热合成制备，平均粒径为 18nm。这些上转换纳米粒子可以通过荧光共振能量转移（LRET）来敏化光捕获藻胆蛋白（R-藻红蛋白）。
