(a) Schematic illustration of the device architecture used for the fabrication of LEDs using CH3NH3PbBr3 perovskite nanoplatelets as an emitter layer. (b) Electroluminescence spectrum obtained from a perovskite nanoplatelets-based LED at different applied voltages. The insets show a photograph of working LED and a TEM image of nanoplatelets employed. Reproduced from Lin et al.32 (c) Device architecture used for the fabrication of LEDs using CsPbBr3NCs as an emitter layer. (d) Emission spectrum of the CsPbBr3 NC film and electroluminescence spectrum of the CsPbBr3-based LED fabricated using the device structure shown in c. Insets show a photograph of working LED and the corresponding log-scale electroluminescence spectra. Reproduced from Zhang et al.38
