In the 1990's, Shuji Nakamura of Nichia found that indium gallium nitride could be used to make the elusive blue kind.
An analogous device that emits ultraviolet radiation can be constructed using diamonds. In 1962, Nick Holonyak, Jr., of General Electric used gallium arsenide phosphide to successfully demonstrate its use. In the 1990's, Shuji Nakamura of Nichia found that indium gallium nitride could be used to make the elusive blue kind. For 10 points, name this solid-state technology that uses a biased semiconductor to achieve greater efficiency than incandescent or fluorescent illumination.
