Surficial Homogenic Effect Enables Highly Stable Deep‐Blue Perovskite Light‐Emitting Diodes

The device performance of deep‐blue perovskite light‐emitting diodes (PeLEDs) is primarily constrained by low external quantum efficiency (EQE) especially poor operational stability. Herein, we develop a facile strategy to improve deep‐blue emission through rational interface engineering. We innovat...
