Retracted: High‐Efficiency, Blue, Green, and Near‐Infrared Light‐Emitting Diodes Based on Triple Cation Perovskite

Highly efficient green, red, and blue perovskite light-emitting diode based metal-oxide charge injection layers are demonstrated. This is an important step toward the realization of next-generation solid-state lighting and devices for use in full-color large-area display applications.
