Physics Nobel Prize to Inventors of Blue Diode Light Source

Two Japanese scientists and a Japanese-born American won the Nobel Prize in physics on Tuesday for inventing blue light-emitting diodes, a breakthrough that has spurred the development of LED technology to light up homes, computer screens and smartphones worldwide.

Isamu Akasaki, Hiroshi Amano and naturalized U.S. citizen Shuji Nakamura revolutionized lighting technology two decades ago when they came up with a long-elusive component of the white LED lights that in countless applications today have replaced less efficient incandescent and fluorescent lights.
