Researchers win Nobel Prize in physics for invention of blue LEDs

Three researchers who succeeded in inventing efficient blue light-emitting diodes (LEDs) where many companies had failed have won the Nobel Prize in Physics.

The Royal Swedish Academy of Sciences on Tuesday announced the award to Isamu Akasaki of Meijo University and Nagoya University, Hiroshi Amano, also of Nagoya University, and Shuji Nakamura of the University of California, Santa Barbara (UCSB).

In its announcement Tuesday in Stockholm, the Royal Swedish Academy of Sciences said that “incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps.” The Nobel committee said the relatively young technology has contributed to saving the Earth’s resources.

Swedish physicist Bjorn Jonson said LED lighting benefits masses of people in some of the world’s most remote regions.

“One and a half billion of people on Earth have no access to electricity grids. That means that they cannot get light, but now with a solar cell, a battery and a LED lamp, they can start to read in the evenings instead of sitting in the darkness,” said Johnson.

Akasaki and Amano are colleagues at Japan’s Nagoya University, while Nakamura is currently working at the University of California in Santa Barbara. The trio will share the $1.1 million attached to the award.

In a telephone call, the Nobel committee congratulated Nakamura and he expressed his delight. “Oh, yeah. Amazing, unbelievable,” he said.

The 2014 Nobel Prize announcements began Monday, when American-British scientist John O’Keefe and husband and wife Norwegians May-Britt and Edvard Moser were awarded the Nobel prize in medicine for their work in discovering the brain’s inner navigation system.

The Nobel Prize in chemistry will be announced Wednesday, followed by the literature prize on Thursday and ending with the prestigious peace prize on Friday.
