LuAG(Pr) Scintillator (LuAG(Pr) Scintillation Crystal)
Praseodymium-doped Lutetium Aluminum Garnet (LuAG:Pr) is an advanced high-performance inorganic scintillation material. It boasts a high density of 6.73 g/cm³, ultra-fast decay time of ~20 ns, and a light yield of 16，000~20,000 photons per MeV, with excellent energy resolution and radiation hardness. It is particularly ideal for time-of-flight positron emission tomography (TOF-PET) and high-energy electromagnetic calorimeter experiments.
OST Photonics provides custom supply of LuAG(Pr) crystals and LuAG(Pr) scintillation screens tailored to your specific needs. We offer a full range of flexible design options to match the unique requirements of different application scenarios and customer projects.

Scintillation Screen Design Options of LuAG(Pr) 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 markings 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).
