The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study has found ...
A research group has demonstrated the ability to produce deep-ultraviolet emission using an LED light source, potentially solving several problems related to quantum efficiency of current devices. The ...
The U.S. Department of Energy recently awarded $11.5 million to install light emitting diode lighting in parks, police stations, an airport runway, baseball fields and city buildings to promote energy ...
