Shuji Nakamura awarded 2014 Nobel Prize in PhysicsOctober 7th, 2014
The 2014 Nobel Prize in Physics has been awarded to Shuji Nakamura, professor of materials and of electrical and computer engineering at the University of California, Santa Barbara, and two others.
The prize is for the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources, and is shared with Isamu Akasaki of Meijo University and Nagoya University, Japan; and Hiroshi Amono of Nagoya University.
According to the Royal Swedish Academy of Sciences, when Nakamura, Akasaki and Amono “produced bright blue light beams from their semiconductors in the early 1990s, they triggered a fundamental transformation of lighting technology. Red and green diodes had been around for a long time, but without blue light, white lamps could not be created. Despite considerable efforts, both in the scientific community and in industry, the blue LED had remained a challenge for three decades.”
