LYSO (Cerium doped Lutetium) is a high-performance inorganic scintillator characterized by its high density, fast decay time, and exceptionally high photon yield. Thanks to its excellent timing resolution and low afterglow, LYSO is widely used in time-of-flight positron emission tomography (TOF-PET), small animal imaging, and high-energy physics detectors.
EBO offers LYSO crystals in a wide range of sizes and geometries, including bars, pixels, and complex array configurations. EBO supports custom fabrication to meet specific detector design requirements. The minimum pixel size EBO can manufacture is 0.2 × 0.2 mm. A variety of surface coatings or reflective materials—such as ESR, BaSO₄, and E20.

GAGG Scintillation Crystal Gadolinium Aluminum Gallium Garnet
Cesium iodide (CsI(Tl)), activated by thallium, is one of the most efficient scintillators discovered so far. CSI Crystal exhibits thallium-activated luminescence with an emission peak at 550 nm and a light output of 45% relative to NaI(Tl). In contrast, cesium iodide activated by sodium (CsI(Na)) features a sodium-activated emission peak at 420 nm and a higher light output (85% of NaI(Tl)). Both materials share properties such as deliquescence, soft and plastic mechanical behavior, radiation resistance, high-temperature tolerance, and fast timing characteristics (for pure CsI). They are widely used in particle detection for high-energy physics experiments, medical SPECT imaging, baggage/container security inspection, industrial level sensing and non-destructive testing, and cosmic ray research in space physics.
