Ion migration can induce overshoot of luminance in normal 3D perovskite light-emitting diode devices and results in reduced lifetime. Here Kim et al. show that the ion migration and overshoot can be suppressed in 3D/2D hybrid perovskites, leading to

Metal halide perovskites (MHPs) have outstanding photophysical properties and are therefore being evaluated as next-generation light emitters. Within just a few years, the efficiencies of polycrystalline perovskite light-emitting diodes (PeLEDs) have

Perovskite light-emitting diodes (PeLEDs) based on three-dimensional (3D) polycrystalline perovskites suffer from ion migration, which causes overshoot of luminance over time during operation and reduces its operational lifetime. Here, we demonstrate
