摘要：

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. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
