Grain engineering for efficient near-infrared perovskite light-emitting diodes

Baek et al. report the formation of a discrete island–convex dome morphology in perovskite by solvent engineering to improve the outcoupling efficiency in NIR LEDs. 2D/3D heterostructures are constructed to further increase the efficiency to 31.4% with a peak radiance of 929 W sr⁻¹ m⁻² at 798 nm.
