Abstract

The color-tunable stacked organic light-emitting devices (SOLEDs) with independently-addressable intermediate Al/Au electrode are examined. High brightness color-tunable SOLED can be achieved by properly optimizing the Al/Au electrode and using appropriate electron- and hole-injection layer. Full-color emission is achieved in a simple device structure with features of (1) only two-unit SOLED, and (2) the intermediate electrode is the Al/Au dual metal layers which are easy to process and have no damage to the organic layer.
