Abstract	Yolk-shell structured Bi2SiO5:Yb3+,Er(3+)upconversion nanophosphors have been successfully synthesizedviaa simple template-assisted route, in which the reaction of Yb3+/Er(3+)co-doped bismuth precursor nanospheres with the silica capping layerin situis ingeniously designed and controlled. The phase transition and morphology evolution are investigated in detail by X-ray powder diffraction and high-resolution electron microscopy to propose the formation mechanism of the yolk-shell nanostructure. The yielded Bi2SiO5:Yb3+,Er(3+)nanophosphors can emit bright green upconversion luminescence under the excitation of a 980 nm laser diode, which enables them to be promising emitters for optoelectronic devices. The potential of the Bi2SiO5:Yb3+,Er(3+)nanophosphors as an optical nanothermometer is also demonstrated. The proposed facile synthetic route, unique yolk-shell nanostructure and good upconversion luminescence performance lead the way to access these lanthanide-doped Bi(2)SiO(5)nanophosphors for applications in biotechnology and optoelectronic devices.
