Abstract

Bright and single band red-emitting NaErF₄:Tm,Gd-based upconversion nanophosphors (UCNPs) were successfully synthesized by the formation of a core/intermediate shell/active shell structure. The NaErF₄:Tm,Gd/NaYF₄:Ca,Yb/NaYF₄:Nd,Yb core/shell/shell UCNPs exhibit intense red light under both 980 and 800 nm near infrared light excitations.
