Fig. 4 |. Perovskite PCDs coupled with the LaBr3:Ce scintillator γ-ray spectroscopy performance.
(a) 57Co γ-ray spectra collected by the perovskite PCD and the SiPM under the same experimental conditions. 137Cs γ-ray spectra collected by (b) the perovskite PCD and (c) the SiPM, and (d) Energy resolution at 662 keV resolved by the perovskite PCD and the SiPM at different temperatures, the error bars represented 5% errors from the Gaussian fitting.
