Abstract

Novel Yb/Er(Tm):Na₃MF₇ (M = Zr, Hf) nanocrystals with intrinsic single-band upconversion emission, in contrast to the routine lanthanide-doped fluoride nanocrystals which show typical multi-band upconversion emissions, are reported for the first time. Specifically, the red upconversion intensity of the Yb/Er:Na₃ZrF₇ nanocrystals is about 5 times as high as that of the hexagonal Yb/Er:NaYF₄ ones with a similar crystal size.
