A novel ion anchoring strategy stabilizes the perovskite phase, yielding ambient stable perovskite films and ultra-stable perovskite light-emitting diodes (PeLEDs) with an unprecedented operational half-lifetime over 37.2 years at 100 cd m and exceeding 27% efficiency, marking a new stability benchmark for next-generation display and lighting applications.
