NaYF4∶Yb,Er@SiO2与Au纳米粒子荧光共振能量传递系统的构建与研究
Studies on The Constructure Based on Luminescnece Resonant Energy Transfer Between NaYF4∶Yb, Er@SiO2 Nanostructure as Donors and Gold Nanoparticle as Acceptors
摘要
Abstract
We present a facile method to integrate NaYF4: Yb, Er upconversion nanoparticles with Au nanoparticles for constructing NaYF4: Yb, Er@ SiO2 @ Au composite nanostructures, in which a silica layer on NaYF4: Yb, Er nanoparticles to make them water-stable and acts as an interface for Au decoration. The green and red emissions of the upconversion nanoparticles can be conveniently adjusted by altering the amount of surrounding Au nanoparticles. These results are positive for the widely exploring applications of upconversion nanoparticles in biological imaging, detection, and sensing.关键词
