First 3D-printed complex inorganic polycrystalline scintillator

YAG:Ce scintillating material was obtained using 3D printing for the first time. A green body was printed using a stereophotolithography approach from co-precipitated powders and then sintered at 1600 °C in air to afford translucent ceramics. The scintillation light yield using 5.5 MeV α-particle excitation was more than 60% higher than that of the reference YAG:Ce single crystal.
