Ce: LuAG crystal (the chemical formula is Ce: Lu3Al5O12) is a scintillation crystal with excellent scintillation properties. Its emission peak is located at 520nm-550nm, which matches well with the photomultiplier tube (PMT) and silicon photodiode (PD).

Ce: LuAG crystal shows stable physical and chemical properties, high thermal conductivity, High density and high effective atomic number, high light output, and fast decay time. Ce: LuAG crystals are widely used in photomultiplier tubes, scintillation screens and other devices to detect high-energy particles, such as α particles, β rays, and γ rays. Because of the excellent scintillation performance of Ce:LuAG crystal, it is widely used in CT, scanning electron microscope and other equipment.
