A strategy to manipulate lanthanide upconversion luminescence via Ce³⁺ doping was demonstrated in nano-structured glass ceramic. Specifically, transparent bulk glass ceramic containing orthorhombic YF₃ nanocrystals was successfully prepared by a melt-quenching and subsequent crystallization procedure, and the lanthanide (Yb/Tm/Ho) activators were evidenced to incorporate into YF₃ crystalline lattice, leading to significantly enhanced upconversion luminescence. Importantly, Ce³⁺ dopants played a key role in modifying Ho³⁺ red to green emission ratio but had no effect on Tm³⁺ blue emission, which was beneficial to producing color-tunable luminescence, including white light, in the glass ceramics.
