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.
Shanghai North Optics offers custom LYSO(Ce) blanks, polished components, scintillation screens, and LYSO(Ce) arrays upon the customer's request, our LYSO scintillation crystals are grown by Czochralski method, the largest diameter of 105mm and a maximum length of 200mm crystals are available.
