Description
LYSO Crystal Overview The LYSO (Lutetium Yttrium Orthosilicate) crystal, specifically doped with cerium (Ce), is a remarkable scintillation material known for its exceptional properties and versatility. Characterized by its monoclinic structure, LYSO is both colorless and transparent, making it an ideal choice for various applications.
Its high light output, short decay time, and impressive radiation hardness are complemented by its high density, making it a superior option in the realm of scintillation crystals. LYSO's emission peak wavelength at 420 nm falls within the sensitive region of photomultiplier tubes (PMT), ensuring effective detection of emitted light. The crystal also boasts stable physical and chemical properties, which enhance its convenience for use in different environments. These attributes collectively make LYSO an excellent scintillation crystal that stands out in its field.
Beyond its scintillation capabilities, LYSO is widely applied in nuclear medicine and high-energy physics, among other areas. Its benefits to detectors include achieving high time resolution, spatial resolution, and miniaturization, making it a valuable component in advanced detection systems.
