Two Japanese researchers and an American scientist have won the Nobel Prize in physics, AP reported Tuesday.
Isamu Akasaki and Hiroshi Amano shared the honors with American Shuji Nakamura for the invention of blue light-emitting diodes, a new energy-efficient and environment-friendly light source.
The Royal Swedish Academy of Sciences said the invention is just 20 years old “but it has already contributed to create white light in an entirely new manner to the benefit of us all”.
Akasaki, 85, is a professor at Meijo University and distinguished professor at Nagoya University.
Amano, 54, is also a professor at Nagoya University while the 60-year-old Nakamura is a professor at the University of California, Santa Barbara.
They triggered a transformation of lighting technology when they produced bright blue light from semiconductors in the 1990s, the Nobel committee said.
On Monday, British-American scientist John O’Keefe split the Nobel Prize in medicine with Norwegian couple May-Britt Moser and Edvard Moser for breakthroughs in brain cell research that could pave the way for a better understanding of diseases like Alzheimer’s.
The Nobel award in chemistry will be announced Wednesday, followed by the literature award on Thursday and the Nobel Peace Prize on Friday.
The economics prize will be announced next Monday.
