Nobel trio win for lighting up our world in blue LED

Two Japanese scientists and a Japanese-born American have won the Nobel Prize in physics for inventing blue light-emitting diodes.

It is a breakthrough that has spurred the development of LED technology to light up homes, computer screens, and smartphones worldwide.

Isamu Akasaki, Hiroshi Amano, and naturalised US citizen Shuji Nakamura revolutionised lighting technology two decades ago when they came up with a long-elusive component for white LED lights.
