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.
