Japanese Physicist Isamu Akasaki, a co-winner of the 2014 Nobel Prize in Physics, has passed away. Akasaki, a professor at the university, had been recognized for the invention which has contributed to bright and energy-saving white light sources, widely known as LED lamps. He was honoured in 1997 by the Japanese government with the Medal with Purple Ribbon, an honour bestowed on those who have made contributions to academic and artistic developments.
In 2014, Akasaki, a professor at Meijo University, shared the Nobel Prize in Physics with physicist Hiroshi Amano, a professor at the University of Nagoya, and Japan-born American Shuji Nakamura, a professor at the University of California, Santa Barbara. He worked with Amano to produce gallium nitride crystals and succeeded in 1989 in creating the world’s first blue LED.
