Isamu Akasaki was a Japanese physicist who was part of the Nobel Prize-winning team that developed blue LED light, a breakthrough that led to the widespread use of LED today.Early LEDs emitted red light.
They were useful in technological applications, but they only provided a very small amount of light. Creating a blue LED was a challenge that many scientists worked on, including Akasaki and his graduate student, Hiroshi Amano.
They successfully developed an LED that emitted blue light, and Shuji Nakamura further refined their process to create a blue LED that produced abundant light.
