LED Pioneers Honored
In November 2003, two of DOE's research partners – Dr. George Craford of Lumileds Lighting and Russell Dupuis of Georgia Institute of Technology – were awarded the 2002 National Medal of Technology. These pioneers were honored for their contributions to the development and commercialization of LED technology. (November 2003)
Size and Performance Breakthroughs in OLED Panels
General Electric Global Research teamed with Cambridge Display Technologies to develop a practical-sized OLED light panel that produces 1200 lumens of quality white light with an efficacy of 15 lumens/watt – on par with today's incandescent bulb technology. This achievement broke two world records. (April 2004) Learn more.
White LED Breakthroughs in Performance, Quality
Lumileds Lighting teamed with Sandia National Laboratories to investigate critical materials issues, including the use of semiconductor nanoparticles ("quantum dots") as luminescent down-converting materials for white LEDs. The nanoparticles produced conversion yields up to 76 percent, a world record. (April 2004) Learn more.
Cantilever Epitaxy R&D 100 Award
Sandia National Laboratories received an R&D 100 Award from R&D Magazine for development of a new process for growing gallium nitride on an etched sapphire substrate. The process, called cantilever epitaxy, promises to make brighter and more efficient green, blue, and white LEDs. (October 2004) Learn more.
Low Voltage White Phosphorescent OLED Achievements
Universal Display Corporation teamed with Princeton University and the University of Southern California to develop low voltage, high efficiency white phosphorescent OLEDs (PHOLED™). The team succeeded in developing a white PHOLED that achieved a record 20 lumens per watt, operating at 6.3 V. (October 2004) Learn more.
