Abstract

Rare earth (RE) ion doped glass ceramics containing hexagonal ${\text{CeF}}_3$ nanocrystals with a mean size of 12 nm were fabricated. Using ${\text{Eu}}^{3+}$ as the structural probe, Stark splitting emissions and the low forced electric dipole ${{}^{5}D}_0\to {{}^{7}F}_2$ transition of ${\text{Eu}}^{3+}$ revealed the partition of RE ions into low-phonon-energy ${\text{CeF}}_3$ nanocrystals. Efficient energy transfers from ${\text{Ce}}^{3+}$ to ${\text{Tb}}^{3+}$ or ${\text{Dy}}^{3+}$ were found, and the energy transfer efficiency was evaluated. Under ultraviolet excitation, intense white-light emission was observed in ${\text{Dy}}^{3+}$-doped samples owing to ${\text{Dy}}^{3+}$ resided in ${\text{CeF}}_3$ crystalline environment, indicating their potential application in white-light-emitting diodes.
