History of the LED
Today, magnesium-doping of gallium nitride remains the basis for all commercial blue LEDs and laser diodes. In the early 1970s, these devices were too dim for practical use, and research into gallium

The birth of the blue LED
The first red LED was created in the 1950s and by the 1960s the pursuit of shorter emission wavelengths had already yielded green LEDs — but blue devices were lacking.
The Blue Laser Diode: Complete Story | PDF | Laser | Laser Diode
This document is a book about the development of the blue laser diode. It discusses key players like Shuji Nakamura who were instrumental in developing blue LEDs using InGaN/AlGaN materials.
Background Story of the Invention of Efficient InGaN Blue‐Light
In the 1980s, all known material systems possessing the necessary properties for blue-light emission had shortcomings, thus negating their utilization in efficient LEDs. Gallium nitride (GaN)
