From: Lithium-doped two-dimensional perovskite scintillator for wide-range radiation detection

Fig. 5

a Alpha particle pulse-height spectra. b Pulse-shape discrimination (PSD) matrix with the shape indicator on y-axis and the measured energy (electron equivalent) on x-axis. The inset with the green and the blue curves shows the normalized average waveforms from both alpha particle and gamma-ray radiation of 137Cs and 241Am sources, respectively. c Pulse-height spectra measured with graphite-moderated Am–Be neutron source of 1:1 Li-(PEA)2PbBr4 crystal. The pulse-height spectra of neutron and 137Cs sources are indicated by red and blue dots, respectively.
