Abstract

We present a facile method to integrate NaYF

∶Yb

Er upconversion nanoparticles with Au nanoparticles for constructing NaYF

∶Yb

Er@SiO

@Au composite nanostructures

in which a silica layer on NaYF

∶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.
