The Nobel Prize in Physics in 2014 was awarded to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura for the invention of efficient blue light- emitting diodes (LEDs). The development of blue LEDs was a crucial step that enabled the creation of bright and energy-saving white light sources, making them essential for modern lighting technology. While the award was specifically for the invention of blue LEDs, the key outcome and widely recognized application is the enablement of white LEDs for general lighting.
