Lanthanum bromide (LaBr₃) is an inorganic ceramic compound composed of the rare-earth element lanthanum and bromine. It is primarily valued as a scintillation material—a substance that emits light when struck by ionizing radiation—making it essential for radiation detection and measurement applications. LaBr₃ is chosen over alternative scintillators in demanding nuclear and medical imaging environments because of its superior energy resolution and fast light output, enabling precise detection of gamma rays and other high-energy particles in settings where accuracy and speed are critical.
