    • Rare-Earth Doped LaF₃ Nanocrystals for Upconversion Fluorescence 

      Yi, Guang-Shun; Chow, Gan-Moog (2006-01)
      Upconversion fluorescent nanocrystals, Yb-Er, Yb-Ho and Yb-Tm co-doped LaF₃ were chemically synthesized. The average particle size was 4.4 nm with a narrow size distribution of ± 0.3 nm. Under the 980 nm NIR excitation, ...
