The synthesis of highly luminescent, colloidally‐stable and organically‐capped silicon nanocrystals (ncSi) and their incorporation into a visible wavelength organic light‐emitting diode (OLED) is reported. By substituting decyl chains with aromatic allylbenzene capping ligands and size‐selecting visible emitting ncSi, superior packing density, enhanced charge transport, and an improved photoluminescence absolute quantum yield of the ncSi is obtained in the active layer of an OLED.
