An LED breakthrough in Korea?
Researchers from Korea claim to have produced the world's first purely white LED (light-emitting diode).
Soo-Young Park, a professor of organic materials for photonics at the Department of Materials Science and Engineering at Seoul National University in Korea, led the group, which includes researchers from the University of Valencia in Spain.
LEDs are much more energy-efficient than incandescent or compact fluorescent lightng (CFL), but the quality of light they can give a room is up for debate.
Because LEDs do not naturally produce white light, getting them to look like they do adds to their production cost, making them … Read more
