Optimizing Emission Stability in Blue Perovskite Light‐Emitting Diodes via Oxygen‐Plasma Treatment of NixOy Hole Transport Layer

Currently, wide‐color gamut perovskite light‐emitting diodes (PeLEDs) are commonly controlled through halide composition tuning. However, the formation of perovskite crystals involving different ion radii of halogens often results in structural fragility and ionic defects, leading to emission instab...
