Abstract

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 boost the outcoupling efficiency from 22% of standard randomly-oriented emitters to 34% in our LEDs.
