University of Utah physicists invented a new “spintronic” organic light-emitting diode or OLED that promises to be brighter, cheaper and more environmentally friendly than the kinds of LEDs now used in television and computer displays, lighting, traffic lights and numerous electronic devices. “It’s a completely different technology,” says Z. Valy Vardeny, University of Utah distinguished […]

OLEDs are the next generation display technology. They are already used in televisions, cell phones and computers, and they are candidates for a vast array of light sources from advertising billboards to indoor and outdoor illumination. Fluorescent OLEDs are typically less efficient at emitting light per unit area than their phosphorescent counterparts. That may be […]

Thomas Alva Edison invented the long-lasting light bulb more than a hundred years ago. The principle of the filament has remained the same to this day – as has its poor yield: The bulb converts only 5 to 10 percent of the invested energy into light, while most of it becomes heat. Fluorescent tubes and […]
