Upconversion luminescence of monodisperse CaF2:Yb(3+)/Er(3+) nanocrystals.
Monodispersed CaF(2):Yb(3+)/Er(3+) nanocrystals have been prepared via a facile wet chemical technology. The upconversion luminescence properties of CaF(2):Yb(3+)/Er(3+) nanocrystals were compared with those of NaYF(4):Yb(3+)/Er(3+) nanocrystals with different phases and particle sizes. The results indicated that CaF(2) is a promising host material for producing desirable upconversion luminescence.
