Efficient white upconversion (UC) luminescence is obtained in Yb 3+ /Eu 3+ doubly-doped optical glass ceramic (GC) for the first time. KYb 3 F 10 nanocrystals are controllably precipitated from the amorphous networks via the inducing of Yb 3+ . Yb 3+ ions are spontaneously confined within the compact fluoride crystal structures to produce efficient blue UC emissions of Yb 3+ -Yb 3+ pairs. Eu 3+ ions are easily incorporated into the KYb 3 F 10 crystal lattices. Owing to the extremely short interionic distance in the crystal structures, intense green UC emissions apart from the red emissions of Eu 3+ are observed, which are not obtained by the traditional Yb 3+ /Eu 3+ doubly-doped GCs. As a result, white UC emissions are synthesized based on the three-primary-color principle and the emission intensities of GCs are dramatically enhanced as compared to glass. The designed GCs provide novel optical gain materials for the promising applications in three-dimensional display, solid-state lighting and tunable fiber lasers.
