Abstract

We propose lead-halide-based perovskite-type organic/inorganic hybrid compounds, e.g. (CH3NH3)PbBr3 and (C 6H13NH3)2PbI4, as a new kind of scintillator to use excitonic luminescence of semiconductor as the signal of radiation detection. Single crystals of the materials were bombarded by an electron pulse (1 to 2 ps) from a linear accelerator and the time profile of the intensity of radiation-induced luminescence were measured by a streak camera. As a result, decay time constants of (CH3NH 3)PbBr3 and (C6H13NH 3)2PbI4 were evaluated to be 160 ps and 45 ps, respectively. These values are much smaller than that of the fast component of BaF2 (600 ps), which is known as one of the quickest responses of scintillators. Consequently, we conclude that the perovskite-type organic/inorganic hybrid compounds are promising ultra-fast scintillators.
