Fabrication of Transparent Cerium-Doped Lutetium Aluminum Garnet (LuAG:Ce) Ceramics by a Solid-State Reaction Method
Polycrystalline, transparent LuAG:Ce ceramics were fabricated by a solid-state reaction method using high-purity Lu2O3, Al2O3 and CeO2 powders. The mixed powder compacts were sintered at 1770°C for 10 h under vacuum and annealed at 1450°C for 20 h in air. The transmittance in the visible light region reaches 70%. The emission spectra at 470–650 nm wavelengths are consistent with that of LuAG:Ce single crystals, and satisfy the property requirements of a scintillator.
