Optimization of the Ultra-fast Scintillation Material for a Sub-nanosecond Timing X-ray Detector

将卤化铅基钙钛矿型有机/无机杂化化合物（R-NH_3）_2(CH_3NH_3)_<m-1>M_m X_<3m-1>作为闪烁体材料进行了优化，并将生长的单晶安装在光电倍增管上制成了x射线传感器。该传感器检测到67.4 keV的x射线，亚纳秒时间分辨率为0.7 ns，检测效率高达24%。与塑料闪烁体相比，这可以将61Ni穆斯堡尔共振的采集时间减少到七分之一。

Lead-halide-based perovskite-type organic/inorganic hybrid compound, (R-NH_3)_2(CH_3NH_3)_<m-1>M_m X_<3m-1>, was optimized as a scintillator material, and an X-ray sensor with the grown single crystal mounted on a photomultiplier tube was developed. The sensor detected 67.4 keV X-rays with a subnanosecond timing resolution of 0.7 ns and a high detection efficiency of 24%. This can reduce an acquisition time of 61Ni Mossbauer resonance to be a seventh in comparison with a plastic scintillator.
