LYSO Crystals

LYSO Crystals


With excellent scintillating performance, Yttrium lutetium silicate crystal (LYSO) is characterized by high yield, fast luminescence decay, high effective atomic number, high density, stable physicochemical properties, no deliquescence, high resolution to γ-ray energy, strong radiation resistance. LYSO is widely applied in the fields of high-energy physics, nuclear physics, oil well drilling, security check, and environmental inspection.
