Lanthanide-doped nanocrystals for bioapplications

Nanoscale ‘HOT’ ArticleLanthanide-doped KLaF4 nanocrystals

Xueyuan Chen and co-workers have synthesised and characterised a variety of water soluble lanthanide-doped KLaF4 luminescent nanocrystals.

Doping with Er3+/Yb3+, Ho3+/Yb3+ or Tm3+/Yb3+ gave upconversion (UC) phosphors, whereas doping with Ce3+/Tb3+ or Eu3+ gave downconversion (DC) phosphors.

 

 

The authors believe that these nanocrystal phosphors have potential for use in bioassays, DNA hybridisation, and bio-imaging.
