Organic Light‐Emitting Diodes: Silicon Nanocrystal OLEDs: Effect of Organic Capping Group on Performance (Small 23/2012)

Pictured is an abstract graphic of a light emitting diode (LED) in which the electroluminescent layer comprises allylbenzene-capped silicon nanocrystals. The use of short aromatic ligands and size-selective precipitation purification methods by G. A. Ozin and co-workers on page 3647 result in superior packing density, enhanced charge transport, and an improved photoluminescence absolute quantum yield of the silicon nanocrystals in the active layer of the LED—a step towards ‘greener’ quantum dot devices.
