Physicist Isamu Akasaki, a co-winner of the 2014 Nobel Prize in physics for inventing the world's first efficient blue light-emitting diodes, has died, Meijo University said Friday. He was 92. The Japan Times reports: Akasaki, born in Kagoshima Prefecture, graduated from Kyoto University in 1952 before working at Matsushita Electric Industrial Co., now Panasonic Corp. He started working at Nagoya University as a professor in 1981 and was later given an honorary title. In 2014, he shared the Nobel Prize with physicist Hiroshi Amano, professor at the university, and Japan-born American Shuji Nakamura, professor at the University of California, Santa Barbara. Akasaki, when he was a professor at Nagoya University, worked with Amano to produce gallium nitride crystals, and succeeded in 1989 in creating the world's first blue LED. Akasaki was honored in 1997 by the Japanese government with the Medal with Purple Ribbon, an honor bestowed on those who have made contributions to academic and artistic developments.
