Abstract

Fast hybrid organic-inorganic two-dimensional (2D) perovskite scintillators with high light yield are measured for their scintillating properties. With a light yield of 17 300 ± 2140 photons/MeV, undoped PEA2PbBr4 crystals already exhibit 100 ± 4 ps coincidence time resolution (CTR) at 511 keV excitation. However, Li-doped PEA2PbBr4 crystals have improved the light yield to 21 400 ± 2140 photons/MeV and showed sub-100 ps CTR. Such CTR values and low-cost manufacturing processes make these 2D perovskite scintillators as promising competitors for commercial lanthanide scintillators in time-of-flight positron emission tomography and for fast timing detectors.
