All‐Solution‐Processed Light‐Emitting Diodes
In article number 2206582, Hilmi Volkan Demir and co‐workers propose all solution‐processed light‐emitting diodes (LEDs) of all face‐down oriented self‐assembled monolayer (SAM) films of colloidal quantum wells (CQWs) and demonstrate them with a high external quantum efficiency of 18.1% and a maximum brightness of 19,800 cd m−2. Here the SAM‐CQWs films...
Semiconductor colloidal quantum wells (CQWs) provide anisotropic emission behavior originating from their anisotropic optical transition dipole moments (TDMs). Here, solution‐processed colloidal quantum well light‐emitting diodes (CQW‐LEDs) of a single all‐face‐down oriented self‐assembled monolayer (SAM) film of CQWs that collectively enable a supreme level of IP TDMs at 92% in the ensemble emission...
