Green LEDs for Efficient Lighting
Abstract:
A new approach to fabricating light-emitting diodes (LEDs) could be used to increase their efficiency by 20 percent while yielding higher-quality light than conventional LEDs. Researchers at the National Renewable Energy Laboratory (NREL) in Golden, CO, have demonstrated the approach by making a yellow-green LED that could soon be combined with other colored LEDs to yield white light. The new LED could help replace current, inefficient methods of generating white light.
