LYSO (Lu1-xYxSi2O5) belongs to the monoclinic system. LYSO(Ce) | Scintillation Crystal is a scintillation crystal with the best combination of properties available at present.

LYSO(Ce) | Scintillation Crystal emits 420 nm light and couples well with PMT under the stimulation of high energy. It also has the advantage of high light yield, short decay time, high density, non-deliquescence, and all around stable physical and chemical properties. Owing to its excellent time and energy resolution, LYSO(Ce) | Scintillation Crystal is widely used in nuclear medicine and nuclear physics.

LYSO(Ce) | Scintillation Crystal is a new type of scintillation material with excellent scintillation properties, including:

  • High light output
  • Short decay time
  • High density and anti-radiation hardness
  • Stable chemical and physical properties

Growth method: Czochralski
Formula: Lu1-xYxSi2O5
Dimensions: Max diameter 65 mm x 180 mm length (maximum boule)
Available items: Monolithic and pixelated LYSO

With access to the complete crystal finishing process, X-Z LAB has the means to provide custom crystals using state-of-the-art fine grinding and polishing machines as well as stable matrix assembly techniques.



LYSO(Ce) | Scintillation Crystal is the ideal positron emission tomography (PET) and scintillator crystal. It has improved energy and timing resolution compared to traditional crystals, such as BGO (bismuth germanate). This is vital to get a clear image and shorten the scanning process.

The global market for PET has been estimated to be around $1 billion worldwide, including the USA, Europe, and Asia, where most of the growth is occurring. The current main PET service suppliers are GE Healthcare, Positron Corporation, Philips Healthcare, Siemens Healthcare, and Raytest.
