Blue LEDS nobly rewarded

The Nobel Prize in Physics for 2014 goes to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura “for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources.” Congratulations!

Gallium nitride and indium gallium nitride were the key materials in making blue LEDs, while cerium(III)-doped yttrium aluminium garnet phosphors convert blue LEDs into white ones.
