Organic light-emitting diodes (OLEDs) for display and lighting applications are most commonly processed by either vacuum deposition or solution processing. Typically, the former approach leads to the highest efficiency devices, readily permitting fabrication of complex device architectures with multiple well-defined layers, such as those often required for efficient devices based on phosphorescent emitters (PhOLEDs). On the other hand, solution-based techniques processing, such as spin-coating, inkjet printing, and roll-to-roll printing, could be attractive for high-volume and large-area OLED fabrication; however, sequential deposition of multiple layers can be challenging, with deposition of a second layer potentially leading to partial dissolution of the first.
