LaBr3(Ce) Scintillator (LaBr3(Ce) Scintillation Crystal)

Cerium-doped Lanthanum Bromide (LaBr₃:Ce) stands out as a high-performance inorganic scintillation crystal. Boasting exceptional light output, superior energy resolution and fast decay time, it outperforms traditional scintillators like NaI(Tl). Ideal for gamma-ray spectroscopy, nuclear medicine, environmental monitoring and space exploration, it enables precise and rapid radiation detection, driving advancements in multiple high-tech fields.

OST Photonics offers encapsulated LaBr₃(Ce) scintillators, high-temperature encapsulated LaBr₃(Ce) scintillators, pixellated LaBr₃(Ce) arrays, and custom-configured LaBr₃(Ce) scintillation detectors to meet specific customer requirements. We also provide LaBr₃(Ce) detector assemblies integrated with silicon photomultipliers (SiPM) upon request.
