The 2014 Nobel Prize in Physics was awarded on Tuesday to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for the invention of efficient blue light-emitting diodes (LEDs), which have “enabled bright and energy-saving white light sources.”
Akasaki, 85, of Japan, is a professor at Meijo University, Nagoya and a distinguished professor at Nagoya University. Since the 1960s, Akasaki has been researching ways to overcome the roadblocks facing high-performance blue LEDs and lasers. For his efforts, he has received the 2009 Kyoto Prize for Advanced Technology and the 2011 IEEE Edison Medal.
Amano, 54, of Japan, is also a professor at Nagoya University.
