Abstract

Abstract : Bright light‐emitting diodes based on solution‐processable organometal halide perovskite nanoplatelets are demonstrated. The nanoplatelets created using a facile one‐pot synthesis exhibit narrow‐band emissions at 529 nm and quantum yield up to 85%. Using these nanoparticles as emitters, efficient electroluminescence is achieved with a brightness of 10 590 cd m −2 . These ligand‐capped nanoplatelets appear to be quite stable in moisture, allowing out‐of‐glovebox device fabrication.
