Abstract: Pure‐red perovskite LEDs (PeLEDs) based on CsPb(Br/I)3 nanocrystals (NCs) usually suffer from a compromise in emission efficiency and spectral stability on account of the surface halide vacancies‐induced nonradiative recombination loss, halide phase segregation, and self‐doping… read more here.
