Simple approach to prepare various sizes of YF3:YbEr nanocrystals in large quantities and their up-converting abilities dependent on preparation times and sodium content are described in this paper. Ionic liquid bmimCl was used in the role of a solvent and NaBF4 as a fluorination agent.
Prepared nanocrystals were characterized by XRD, TEM and up-conversion measurements. The method is suitable for preparation of large quantities of nanocrystals and could be easily adapted and used for relevant important pharmaceutical applications.
