LaBr3 (Ce) Scintillation Crystal Description:
LaBr3 (Ce) scintillation crystal is a type of scintillation crystal material. The LaBr3 (Ce) scintillator is a salt compound composed of lanthanum and bromine and belongs to a generation of inorganic scintillators used for gamma radiation detection. Its light yield is between 1.3 and 1.7 times that of NaI:Tl, and its decay time is 1/20 of that of NaI:Tl. Lanthanum bromide scintillators offer quantifiable energy resolution. LaBr3 (Ce) scintillators exhibit fast light decay times, which enable the measurement of energy resolution.
