Abstract: Optical and scintillation properties of pure GdBr3 and GdBr3:2% Ce3+ are presented. Under optical excitation, Ce3+ luminescence is observed between 350 and 550 nm with maxima at 413 and 446 nm. The Stokes shift is ~3400 cm1. GdBr3:2% Ce3+ shows a high light output of 44 0004000 photons per MeV of absorbed g-ray energy. The scintillation decay curve can be characterized by three decay components with decay times of 20.00.1, 21212 ns and 13.50.5 ms, respectively.
