LYSO(Ce) Crystal

LYSO(Ce) crystals are known for their excellent scintillation properties, including high light yield, fast decay time, and good energy resolution. These properties make them well-suited for detecting and measuring ionizing radiation, such as gamma rays and positrons.


Wavelength of Emission Peak 420nm
Light Output30,000ph/MeV
Decay Constant40ns
Anti-radiation1 x 108rad
Refractive Index1.82/

LYSO(Ce) crystals were produced by CZ technique in Epic crystal since 2013, and it has increasingly been optimizing in order to achieve larger dimension and stable performance. Now crystal ingot can be produced at diameter 90 mm x 200 mm length in commercialized volume.

Meanwhile, we have a completed set of further processing equipment, including the line cutting, inner circle cutting machine, and the grinding and polishing capability, those enable us to handled customized dimensions and shape of LYSO(Ce) crystals from customers. Additionally we own advanced arrays and matrices assembly production line, reflectors or separators to be applied include Barium Sulfate(BaSO4), Enhanced Specular Relfector(ESR, 3M), Teflon or others based on requirement.

In medical imaging, LYSO crystals are used in positron emission tomography (PET) scanners. LYSO crystals are also utilized in high-energy physics experiments, particularly in calorimeters for detecting and measuring the energy of particles produced in particle collisions.
