Paper Title:
Synthesis of Yb3+/Tm3+Co-Doped MF2 (M=Ca,Sr,Ba) Nanocrystals with Blue Up-Converted Fluorescence
  Abstract

A series of MF2:Yb3+/Tm3+(M=Ca, Sr, Ba) upconverted nanocrystals were synthesized by hydrothermal method. Polyvinylpyrrolidone(PVP) is an surfactant which can render the nanocrystals dispersible in water and ethanol. Upconverted emission was also detected in the red and NIR regions of the spectrum and assigned to the 1G4-3F4 (centered at 650 nm) and 3H4 -3H6 (centered at 800 nm) transitions, respectively. In addition, MF2:Yb3+/Tm3+ NCs show bright blue upconverted emission under the 980 nm excitation. As-synthesized MF2:Yb3+/Tm3+ luminescent NCs might find some potential applications in areas of photoluminescence and displays
