Physics Nobel Prize 2014 Has Been Awarded to The Blue LED Japanese Inventors
Hiroshi Amano and Isamu Akasaki from Nagoya University and Shuji Nakamura works separately at Nichia LED manufacturer in Tokushima Japan are the three physics prize winners for 2014, being awarded for their invention of the blue LED. Definitely is the key to modern energy in color lighting. These Japanese scientists who invented the first efficient blue LEDs in the first announcement of the Blue LED in 1993 have received the 2014 Nobel Prize in Physics.
The LED is a semiconductor device made from a combination of chemically
polarised semiconductors. A blue LED is coated with a white phosphor, and the first was pioneered by Nichia chemicals in Japan in 1996.
