Hexamethylene Diisocyanate-Modulated Mixed-Halide Perovskite Enables Efficient and Stable Blue Light-Emitting Diodes
{{output}}
Perovskite light-emitting diodes (PeLEDs) have emerged as promising candidates for next-generation displays, yet blue PeLEDs significantly lag behind their green/red counterparts. The inferior performance of blue PeLEDs arises from two principal challenges: tr... ...
