Abstract:

70904 Because general lighting is responsible for more than 20% of U.S. energy consumption, predominantly from traditional incandescent and fluorescent lights, new broadband white lighting sources are sought that offer significant gains in power efficiency and color quality with less environmental impact. Highly-efficient phosphorescent organic lighting emitting device (OLED) technology has created enthusiasm as a possible solution, but significant engineering challenges remain before the necessary targets in power efficiency, operating lifetime, and manufacturing costs can be achieved. This project will demonstrate and develop high-efficiency broadband white light sources using a single- or double-doped phosphorescent organic light emitting device (OLED), utilizing combined monomer and excimer excited states. In Phase I, single- or doubled-doped phosphorescent OLEDs will be evaluated to identify the best structure for efficient, broadband white emission. Innovative emissive and carrier transporting materials will be explored to further enhance power efficiency and color quality in these structures. Ultimately, a white source with excellent color quality, CIE (0.32, 0.32) with a Color Rendering Index of > 80, and power efficiency greater than 5 lumens/Watt at lighting luminance levels of 800 cd/m2 will be demonstrated. Commercial Applications and Other Benefits as described by the awardee: An energy-efficient, long-lived, solid-state white organic light emitting device (OLED), built on flexible plastic film, should find application in diffuse lighting applications in the commercial, residential, and industrial sectors. Because of its thin, lightweight form, this product should also find use in novel architectural, automotive, and wearable electronic applications.
