Room-Temperature-Grown FAPb0.5Sn0.5I3 Polycrystalline Thick Films for Self-Powered X-Ray Detectors With High Sensitivity and Low Detection Limit.
Perovskite polycrystalline thick films are promising for x-ray detection and imaging, yet the simultaneous realization of high sensitivity and a low detection limit remain difficult due to the trade-off between transport and ion migration. Herein, we report the preparation of FAPb0.5Sn0.5I3 (FA = CH(NH2)2) perovskite p...
