By applying intense-pulsed light (IPL) post-treatment to zinc-oxide nanoparticles (ZnO NPs) to stabilize the hole-electron injection within the quantum-dot emission layer (QD EML) of ink-jet printed quantum-dot light-emitting diodes (QLEDs), the device lifetime properties have been remarkably improved.
