LYSO Crystal

Cerium-doped Lutetium Yttrium Oxyorthosilicate Crystal ((Lu,Y)2SiO5:Ce, namely LYSO:Ce), is colorless and transparent, characterized by monoclinic structure. LYSO not only has excellent scintillation properties such as high light output, short decay time, high density and radiation hardness; but also has its emission peak wavelength 420 nm located in the sensitive region of PMT, and hence the emission can be effectively detected; besides, it has stable physical and chemical properties and hence is convenient for application. Therefore, LYSO is an excellent scintillation crystal.
LYSO can be widely applied in the fields of medicine, high-energy physics and so on. It benefits detectors for obtaining high time resolution, spatial resolution and miniaturization.
