LuAG(Ce) Scintillator (LuAG(Ce) Scintillation Crystal)
Cerium-doped Lutetium Aluminum Garnet (LuAG:Ce) is a high-performance inorganic oxide scintillation material. It has a high density of ~6.73 g/cm³, fast decay time of 50–70 ns, and a light yield of 25,000–30,000 photons per MeV, with excellent chemical stability and radiation hardness. It is widely used in high-resolution X-ray imaging, TOF-PET, high-energy particle detection and industrial non-destructive testing, becoming a widely favored advanced scintillation material.
OST Photonics can provide LuAG(Ce) crystals and LuAG(Ce) scintillation screens customized to your requirements. We offer a full range of flexible design options to match the unique needs of different application scenarios and customers.

Scintillation Screen Design Options of LuAG(Ce) Scintillators
Freestanding ultra-thin scintillation screen.
Ultra-thin scintillation screens can be coupled to a substrate with optical adhesives in order to achieve better optical readout.
Scintillation screens can be inserted into frames(Aluminum, Stainless steel) for easier manipulation.
We can provide customized marking such as a grid, cross or scale on the surface of the screen for easier beam visualization.
We can provide various coating on the surface of the screen upon request, such as reflection coatings(Al, Au, Ag, etc.), AR coating, diffusion painting(TiO2, Al2O3), and conductive coatings(Al, ITO, C).
