High Performance Solution-Processed PhOLEDs

Samson A. Jenekhe, University of Washington, DMR 0805259

High-performance multilayered PhOLEDs fabricated by novel solution-processing method.

Phosphorescent organic light-emitting diodes (PhOLEDs) are of growing industrial interest for applications in next-generation full-color display panels, flexible displays, and solid-state lighting. However, high-performance PhOLEDs are currently made by expensive vacuum deposition processes. We have successfully fabricated highly efficient polymer-based blue PhOLEDs by developing a novel, low-cost, solution-processing method and new solution-processable electron-transport materials such as TQB. The new results show the way towards high performance and low-cost multilayered PhOLEDs by solution-processing. They also provide new insights into solution-processing strategies that are broadly applicable to green, red, and white OLEDs as well as other multilayered organic electronic devices.

  • Education:
  • The project provides excellent opportunities for the education of scientists and engineers in the multidisciplinary field of organic electronics, which requires integration of knowledge of chemistry, physics, and engineering.
  • Graduate students, post-doctoral fellows, and undergraduate students as well as international exchange students from around the world are performing research in the lab.
  • Outreach:
  • The Engineering Bridge Program (EBP) at the University of Washington is designed to motivate incoming first-year underrepresented minority pre-engineering undergraduate students.
  • During the EBP design lab session, the students learn about the engineering profession, are introduced to engineering system and design, and are engaged in the academic community that will become a vital part of their successful engineering careers.
