Current Position: Home » Products » Ce:LYSO

Ce:LYSO crystal (chemical formula Ce:Lu2(1-x)Y2xSiO3) is a new type of scintillation crystal with excellent scintillation properties. The emission peak of Ce:LYSO is about 410 nm. Which matches well with the photomultiplier tube (PMT) and silicon photodiode (PD).

Ce:LYSO crystal exhibits stable physical and chemical properties, high thermal conductivity. It also shows high light output, and fast decay time (about 40ns) and high energy resolution. Ce: LYSO crystals are widely used in photomultiplier tubes, photoelectric counters, scintillation screens and medical equipment, high energy physics, well-logging, x-ray detection, γ-ray radiography.
