Invention of blue LEDs wins physics Nobel

07.Oct.14, 20:13; Icon 941; Date 0; Attitude +0 | 0 | -0

Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura made the first blue LEDs in the early 1990s.

By combining blue light with existing red and green LEDs, this enabled a new generation of bright, energy-efficient white lamps as well as LED screens.

The winners will share prize money of eight million kronor (£0.7m).

They were named at a press conference in Sweden, and join a prestigious list of 196 other Physics laureates recognised since 1901.

Prof Nakamura, who was woken up in Japan to receive the news, told the press conference, "It's unbelievable."

Making the announcement, the Nobel jury emphasised the usefulness of the invention, adding that the Nobel Prizes were established to recognise developments that delivered "the greatest benefit to mankind".

"These uses are what would make Alfred Nobel very happy," said Prof Olle Inganas, a member of the prize committee from Linkoping University.

The committee chair, Prof Per Delsing, from Chalmers University of Technology in Gothenburg, emphasised the winners' dedication.

"What's fascinating is that a lot of big companies really tried to do this and they failed," he said. "But these guys persisted and they tried and tried again - and eventually they actually succeeded."
