Abstract
This brief communication presents our work to determine the absolute light yield and quantum efficiency of LaBr3:Ce scintillator by comparison and also by direct pulse measurement method using SiPM. The first part presents use of the simpler comparison method to determine the light yields of different scintillators using the known yield of NaI(Tl) as reference. In the second part we have determined the absolute light yield and quantum efficiency of LaBr3:Ce crystal by using a SiPM photo detector. Our measured value is in good agreement with the light yield reported by previous measurements using PMT and excitation fluorescence spectroscopy. Quantum efficiencies for scintillation detectors have been determined by using both PMTs and photo detectors, namely APDs by previous authors. This communication is possibly the first report on the determination of quantum efficiency of LaBr3:Ce using SiPM photo detector. The simple and effective method presented here would allow to determine the light yield of any scintillation detector.
