| Abstract: Water-soluble fluorescent LaF3∶Ce,Tb nanocrystals were synthesized rapidly by using a simple route in aqueous solution at 75 ℃. The water-soluble, small nanocrystals with an average diameter of 14 nm were demonstrated to be biocompatible and exhibited bright fluorescence in living hepatocellular carcinoma cell line HCCLM6 cells. The results indicate that the LaF3∶Ce,Tb nanocrystals have the potential to be used as an alternative biological fluorescence probe. |
