Cerium-doped silicate yttrium lutetium, Ce: LYSO or LYSO (Ce) crystal in short, is a Cerium doped and lutetium based scintillation crystal. LYSO (Ce) crystal is a new type of scintillation material that has excellent properties: high density, short decay time, high light output, anti-radiation. LYSO (Ce) crystal is also a reliable scintillation material with stable chemical and physical properties. LYSO(Ce) is ideal for applications that require higher throughput, better timing, and energy resolution, including time-of-flight Positron Emission Tomography (PET) scanning machines. Gamma-ray detectors based on Cerium doped LYSO hold broad prospects in fields like Nuclear Medical Imaging, High Energy Physics, Nuclear Physics, etc.
