| 英文摘要 | A series of monodisperse ultrasmall Ba2YbF7 nanocrystals with intense upconversion emission were synthesized via a facile solvothermal method by using oleic acid as capping ligands. X-ray diffraction (XRD) and transmission electron microscopy (TEM) assays revealed that the as-synthesized Ba2YbF7 nanocrystals are of cubic structure, rather than the reported tetragonal structure. The cell parameter of the particles is 5.918 angstrom. The Er3+ or Tm3+ doped Ba2YbF7 nanocrystals with the size of sub-10 nm can give an intense upconversion emission under the 980 nm laser excitation and the upconversion processes were discussed. The Ba2YbF7 nanocrystals show a potential application as a bioimaging agent. (C) 2011 Elsevier B.V. All rights reserved. |
