Scintillation Properties Of A Crystal Of (C6h5(Ch2)(2)Nh3)(2)Pbbr4

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 x 6 x 1 mm(3) single crystal of bis(phenethylammonium) tetrabromoplumbate(II), (C6H5(CH2)(2)NH3)(2)PbBr4. Excitation, emission, pulse-height and decay-time spectra are presented. The light yield is 10,000 photons per MeV, measured at 662 keV gamma-ray energy. The main decay time under pulsed x-ray excitation is 9.4 ns.
