By controlling the elemental composition, nucleation time, and surface ligands of mixed-halide perovskites, a nanocubic superlattice was achieved. The nanocubic superlattice-based bright red light-emitting diodes demonstrated an exceptional maximum external quantum efficiency of 10.75% and improved operational lifetime.
