Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Enhanced Operational Stability of Carbene‐Metal‐Amide Organic Light‐Emitting Diodes by Reducing Electron Accumulation on the Emitter

open access: yesAdvanced Optical Materials, EarlyView.
Carbene‐metal‐amide (CMA) organic LEDs suffer from poor stability despite submicrosecond excited‐state lifetimes. Here, we show that electron accumulation on CMA emitters triggers bond cleavage, while poor electron transport amplifies OLED instability.
