N2 - Recently, three-dimensional (3D) halide perovskites were considered as X-ray detection materials because of their high mobility, carrier lifetime, and absorption of X-ray radiation. However, their detection sensitivity and instability at extreme conditions and environments still require optimization. In our present research work, we report using one-dimensional (1D) inorganic halide perovskite CsPbI3 crystals for stable X-ray detection. Remarkably, an X-ray detector made of CsPbI3 has a high sensitivity of 2.37 mC·Gy-1·cm-2, which is an order of magnitude greater than that of detectors using 3D halide perovskites reported previously. The high-sensitivity X-ray detection of CsPbI3 crystals is attributed to their high resistivity of 7.4 × 109 ω·cm and large carrier mobility-lifetime product of 3.63 × 10-3 cm2·V-1. Our investigation demonstrates the quite promising applications of X-ray detectors made of the low-dimensional perovskite crystals.
