Currently, one-dimensional all-inorganic CsPbX₃ (X = Br, Cl, and I) perovskites have attracted great attention, owning to their promising and exciting applications in optoelectronic devices. Herein, we reported the exploration of superior photodetectors (PDs) based on a single CsPbI₃ nanorod. The as-constructed PDs had a totally excellent performance with a responsivity of 2.92 × 10³ A·W^–1 and an ultrafast response time of 0.05 ms, respectively, which were both comparable to the best ones ever reported for all-inorganic perovskite PDs. Furthermore, the detectivity of the PDs approached up to 5.17 × 10¹³ Jones, which was more than 5 times the best one ever reported. More importantly, the as-constructed PDs showed a high stability when maintained under ambient conditions.

基于全无机钙钛矿CsPbI ₃纳米棒的卓越光电探测器，具有超快响应和高稳定性

目前，一维全无机CsPbX ₃（X = Br，Cl和I）钙钛矿因其在光电子器件中的广阔前景和令人兴奋的应用而备受关注。在这里，我们报告了基于单个CsPbI ₃纳米棒的高级光电探测器（PD）的探索。如此构造的PD的响应速度为2.92×10 ³ A·W ^–1，响应时间仅为0.05 ms，具有极好的性能，这与有史以来针对全无机钙钛矿PD的最佳记录相比具有可比性。。此外，PD的检测率高达5.17×10 ¹³琼斯（Jones），是有史以来最佳报道的5倍以上。更重要的是，当维持在环境条件下时，如此构造的PD显示出高稳定性。
