YSO(Ce) Scintillator (YSO(Ce) Scintillation Crystal)
Cerium-doped yttrium orthosilicate (YSO:Ce) is a high-performance inorganic scintillation crystal with a density of 4.5 g/cm³ and a fast scintillation decay time of ~50–70 ns. It delivers a high light yield of around 10,000~2,8000 photons per MeV, with a main emission peak at 420 nm matching conventional photodetectors. YSO:Ce features outstanding radiation hardness, excellent thermal stability and non-hygroscopicity, maintaining stable performance in high-radiation environments. It is widely used for gamma-ray detection, positron emission tomography and high-energy particle physics experiments.
OST Photonics can supply YSO:Ce crystals, YSO:Ce scintillation screens and YSO:Ce detector arrays tailored to your requirements, with a full range of design options available.
Application
