Technology 101: The Illusive Blue LED – From Myth to Reality
The blue LED, a pivotal innovation in lighting technology, was developed in the early 1990s by Shuji Nakamura, along with Isamu Akasaki and Hiroshi Amano. This invention was significant enough to earn them the Nobel Prize in Physics in 2014. Blue LEDs are essential because they have a higher energy gap, allowing for the production of blue light, which, when combined with red and green LEDs, can create white light. This advancement has led to energy-efficient lighting solutions that are revolutionizing industries and consumer products worldwide. Photo by panumas nikhomkhai
