Abstract

In inverted quantum-dot light-emitting-diodes (QD-LED), it is important to use orthogonal solvent for hole-transport layer(HTL). In addition, modulating work function of each layer is good way to enhance carrier injection barrier. In this research, we confirmed the viability of usage of a solvent, named gamma- valerolactone (GVL) for forming hole transport layer (HTL). By using the solvent, current density, luminance, roll-off characteristics were enhanced, and highest occupied molecular orbital (HOMO) level was changed, which can enhance the hole injection.
