Invention of blue LEDs wins physics Nobel
The 2014 Nobel Prize for physics has been awarded to a trio of scientists in Japan and the US for the invention of blue light emitting diodes.
Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura made the first blue LEDs in the early 1990s.
This enabled a new generation of bright, energy-efficient white lamps, as well as colour LED screens.
The winners will share prize money of around 140’000 US Dollars.
Today, blue LEDs are found in people's pockets around the world, inside the lights and screens of smart-phones.
