Compared to efficient green and near‐infrared light‐emitting diodes (LEDs), less progress has been made on deep‐blue perovskite LEDs. They suffer from inefficient domain [various number of PbX6− layers (n)] control, resulting in a series of unfavorable issues such as unstable color, multipeak profil...
