Scintillation properties of a crystal of (C6H5(CH2)2NH3)2PbBr4

For the first time results obtained from gamma-ray excitation of a low-dimensional lead-halide-based perovskite-type organic-inorganic scintillator crystal are presented. Scintillation and luminescence properties have been studied of a 5 × 6 × 1 mm
