Stockholm: The Nobel Prize in Physics 2014 was awarded jointly to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources".
Twenty one Nobel Laureates are born in Japan including Akasaki, Amano and Nakamura. Out of the 21 Nobel Laureates, 10 are Physics Laureates.
The Royal Swedish Academy of Sciences said, " In the spirit of Alfred Nobel the Prize rewards an invention of greatest benefit to mankind; using blue LEDs, white light can be created in a new way. With the advent of LED lamps we now have more long-lasting and more efficient alternatives to older light sources."
The laureates triggered a transformation of lighting technology when they produced bright blue light from semiconductors in the 1990s, something scientist had struggled with for decades, the Nobel committee said.
Using the blue light, LED lamps emitting white light could be created in a new way.
"As about one fourth of world electricity consumption is used for lighting purposes, the LEDs contribute to saving the Earth's resources," the committee said.
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, completing the 2014 Nobel Prize announcements.
Worth 8 million kronor ($1.1 million) each, the Nobel Prizes are always handed out on December 10, the anniversary of prize founder Alfred Nobel's death in 1896. Besides the prize money, each laureate receives a diploma and a gold medal.####
