This project is demonstrating an efficient and stable white organic light-emitting diode (WOLED) using a single emitter on a planar glass substrate. Current WOLED technology requires the use of multiple emissive materials, which are expensive to manufacture and also generate color instability and color aging issues, affecting WOLED performance and operational lifetime. Simplifying device fabrication, increasing the robustness of materials, and providing more cost-effective alternates to current iridium-based phosphorescent emitters can reduce WOLED fabrication costs and improve performance. Nationwide, lighting buildings costs $58 billion a year and consumes about 22% of all electricity generated. A single-doped WOLED that addresses manufacturing and performance issues can help meet the targeted cost of organic solid-state lighting established in the U.S. Department of Energy Building Technologies Office Multi-Year Research, Development, and Demonstration Plan.
