Major step taken on the path to ultra-high- efficiency organic LED lighting

Ordinary light bulbs are only 2–3 percent efficient at converting electrical energy into light, and even today’s green compact fluorescent and LED-based bulbs are only 8–14 percent efficient. But LEDs made from organic-polymer semiconductors, or organic LEDs (OLEDs), could theoretically exceed 40-percent efficiency, dramatically reducing energy costs and fossil fuel use. One of the major hurdles in reaching this goal is obtaining all-purpose white light from every pixel in an OLED by combining both fluorescent and phosphorescent emissions—something recently demonstrated by a Los Alamos scientist and his external collaborators.
