What did Isamu Akasaki invent?
blue light-emitting diodes
Isamu Akasaki, a Japanese physicist who helped develop blue light-emitting diodes, a breakthrough in the development of LEDs that earned him a Nobel Prize and transformed the way the world is illuminated, died on Thursday in a hospital in Nagoya, Japan. He was 92.

How blue LED was invented?
When Isamu Akasaki, Hiroshi Amano and Shuji Nakamura produced bright blue light beams from their semi-conductors in the early 1990s, they triggered a fundamental transformation of lighting technology. Red and green diodes had been around for a long time but without blue light, white lamps could not be created.
What kind of research did Isamu Akasaki do?
Dr. Isamu Akasaki conducted persistently intensive research on gallium nitride (GaN) for many years toward the realization of blue light-emitting diodes (LEDs). His efforts culminated in the pioneering realization of GaN-based p-n junctions, which were believed to be practically impossible.
When did Isamu Akasaki invent the GaN LED?
Isamu Akasaki (赤崎 勇 Akasaki Isamu, born January 30, 1929) is a Japanese engineer and physicist, specializing in the field of semiconductor technology and Nobel Prize laureate, best known for inventing the bright gallium nitride ( GaN) p-n junction blue LED in 1989 and subsequently the high-brightness GaN blue LED as well.
When did Isamu Akasaki win the IEEE Edison Medal?
Akasaki is an IEEE Fellow and 2011 winner of the IEEE Edison Medal, “For seminal and pioneering contributions to the development of nitride-based semiconductor materials and optoelectronic devices, including visible wave length LEDs and lasers.”
When did Akasaki get the title of Distinguished Professor?
Nagoya University gave Akasaki the title of distinguished professor in 2004 and named the Akasaki Institute, completed in 2006, in his honour. Prior to Akasaki’s work in the 1980s, scientists had produced LEDs that emitted red or green light, but blue LEDs had been considered impossible or impractical to make.
