Abstract

Rare earth (RE) ion doped glass ceramics containing hexagonal CeF 3 nanocrystals with a mean size of 12 nm were fabricated. Using Eu 3 + as the structural probe, Stark splitting emissions and the low forced electric dipole D 5 0 F 7 2 transition of Eu 3 + revealed the partition of RE ions into low-phonon-energy CeF 3 nanocrystals. Efficient energy transfers from Ce 3 + to Tb 3 + or Dy 3 + were found, and the energy transfer efficiency was evaluated. Under ultraviolet excitation, intense white-light emission was observed in Dy 3 + -doped samples owing to Dy 3 + resided in CeF 3 crystalline environment, indicating their potential application in white-light-emitting diodes.
