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, the green, red and blue emission bands from these nanocrystals were observed, respectively. These nanocrystals have potential applications as bio-probes and displays. / Singapore-MIT Alliance (SMA)
