Intragrain 3D perovskite heterostructure for high-performance pure-red perovskite LEDs
Nature, Published online: 07 May 2025; doi:10.1038/s41586-025-08867-6To increase the efficiency, brightness and stability of next-generation light-emitting diodes (LEDs), the microstructure of CsPbI3-xBrx metal-halide perovskite, a good pure-red emitter, was altered to fix hole leakage, which was identified as decreasing efficiencies in overworked LEDs.
