Efficient charge carrier injection is one of the most important factors to achieve high performance quantum dot (QD) light-emitting diodes (QLEDs). Here, we investigated the effects of charge carrier injection properties on the QLED performance by modifying the surface ligands of QDs and by adopting an interlayer between the QD layer and the charge transport layer.
