Dual valence Eu ‐doped transparent glass‐ceramics containing LuPO 4 nanocrystals were fabricated by melt‐quenching technique in air atmosphere. Their luminescent properties were systematically investigated by excitation, emission spectra, and decay lifetime measurements. The prominent Stark splitting, low forced electric‐dipole 5 D 0 – 7 F 2 transition and long decay lifetimes of Eu 3 + emission for glass‐ceramics reveal the incorporation of Eu 3 + into LuPO 4 nanocrystals. The enhanced Eu 2 + emission and reduction mechanism of Eu 3 + to Eu 2 + after crystallization are discussed briefly. Our results indicate that transparent LuPO 4 glass‐ceramics may find applications in photonics.
