Multistage Fluorination in a Metal‐Free Perovskite Ferroelectric Enables Multidirectional Self‐Powered X‐Ray Detection

ABSTRACT Metal‐free perovskites (MFPs) have emerged as eco‐friendly candidates for next‐generation x‐ray detection. However, their development is severely hindered by poor material stability and the reliance on high driving voltages, which exacerbate device complexity and operati...
