Did you know?
The blue LED is a semiconductor that glows blue when electricity is passed
through it. Of the three primary colors for light, the red and green LEDs were
invented more than 20 years earlier; the blue LED, however, proved to be
elusive. In 1993, the blue LED was developed and soon brought to market
owing to a new technology devised by Prof. Shuji Nakamura. Its world-wide
success in consumer markets has been spectacular – as fascinating as the
intensive and mysterious glow of the blue LED itself.
