Lutetium-yttrium oxyorthosilicate, also known as LYSO, is an inorganic chemical compound with main use as a scintillator crystal. Its chemical formula is Lu2(1-x)Y2xSiO5. It is commonly used to build electromagnetic calorimeters in particle physics. LYSO crystals have the advantages of high light output and density, quick decay time, excellent energy resolution.
The biggest application fields are the major used in life science is PET (positron emission computed tomography (ct) imaging device), including clinical medicine, drugs and pharmacokinetics, biological experiments, such as health care.
