我们研制了一种使用苯乙胺溴化铅（PhE-PbBr（4））的有机-无机钙钛矿闪烁体的快速X射线探测器。闪烁体具有占主导地位的光发射，具有9.9 ns的快速衰减时间。使用装有0.9 mm厚PhE-PbBr（4）晶体的X射线检测器，通过同步辐射检测（61）Ni中的核共振散射（第一激发能级：67.41 keV;寿命：7.6 ns）。利用该探测器，我们成功地记录了（61）Ni衰变γ射线，时间分辨率为0.7ns（半峰全宽），探测效率为24%。
We have developed a fast x-ray detector using an organic-inorganic perovskite scintillator of phenethylamine lead bromide (PhE-PbBr(4)). The scintillator had a dominant light emission with a fast decay time of 9.9 ns. An x-ray detector equipped with a 0.9-mm-thick PhE-PbBr(4) crystal was used to detect nuclear resonant scattering in (61)Ni (the first excited level: 67.41 keV; lifetime: 7.6 ns) by using synchrotron radiation. With this detector, we could successfully record the decaying gamma rays emitted from (61)Ni with a time resolution of 0.7 ns (full width at half maximum) and a relatively high detection efficiency of 24%.
