The🕵️‍♂️🕵️‍♀️ invention of the blue LED, a pivotal development in lighting technology, is credited to a team of Japanese scientists: Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura. Their work, primarily in the early 1990s, involved creating efficient blue LEDs using gallium nitride (GaN) and indium gallium nitride (InGaN). This breakthrough enabled the creation of white LEDs by combining blue LEDs with a phosphor material, and it also paved the way for full-color LED displays. #science #educ
