Proton-transfer-induced 3D/2D hybrid perovskites suppress ion migration and reduce luminance overshoot

Mohammad Khaja Nazeeruddin, Emad Oveisi, Hobeom Kim

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 3D/2D ...
