Invention of Blue LED Laser and Solid State Light with Shuji Nakamura

Shuji Nakamura discusses the way in which his invention grew to be what it is by starting with the work of growing high-quality gallium nitride (GaN) crystals in 1991 to demonstrating highly luminescent, blue light-emitting diodes (LEDs) in 1994. The resulting revolution in generating white light has had a tremendous impact on society by providing highly efficient, robust, portable, non-toxic, battery-operable light sources.
