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.
