Mixed low‐dimensional metal halide perovskite single crystal for low‐detection‐limit x‐ray detection via oriented ion migration

InfoMat, Volume 6, Issue 10, October 2024.
We report a new mixed low‐dimensional (1D–0D) organolead halide perovskite single crystal with a size of 5 mm and well‐defined crystallinity, showing unique polarized photoluminescence and oriented ion migration behavior. Based on the 1D–0D crystal, we have successfully obtained a high‐sensitivity x‐ray detector with an ultra‐low detection limit of 152.
