About Lu3Al5O12 (Lutetium aluminium garnet, LuAG)

Lutetium aluminium garnet (Lu₃Al₅O₁₂, or LuAG) is a synthetic garnet crystal. Owing to its outstanding properties, such as high density, high thermal conductivity, and good transparency in the visible and near-infrared regions, it's widely used in scintillator applications for high-energy photon detection. Additionally, LuAG has been studied as a potential host material for solid-state lasers, particularly when doped with rare-earth ions. Its transparency and luminescent characteristics make it valuable in various optical and photonic devices.
