Bright and single band red-emitting NaErF 4 :Tm,Gd-based upconversion nanophosphors (UCNPs) were successfully synthesized by the formation of a core/intermediate shell/active shell structure. The NaErF 4 :Tm,Gd/NaYF 4 :Ca,Yb/NaYF 4 :Nd,Yb core/shell/shell UCNPs exhibit intense red light under both 980 and 800 nm near infrared light excitations.
