According to the official press release,
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2014 to
Meijo University, Nagoya, Japan and Nagoya University, Japan
Nagoya University, Japan
University of California, Santa Barbara, CA, USA
“for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources”
Isamu Akasaki, Hiroshi Amano andShuji Nakamura produced bright blue light beams from their semi-conductors in the early 1990s,
They succeeded where everyone else had failed. Akasaki worked together with Amano at the University of Nagoya, while Nakamura was employed at Nichia Chemicals, a small company in Tokushima. Their inventions were revolutionary. Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps.
The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids: due to low power requirements it can be powered by cheap local solar power.
The invention of the blue LED is just twenty years old, but it has already contributed to create white light in an entirely new manner to the benefit of us all.
