Japanese scientist

Isamu Akasaki

, awarded the Nobel Prize in Physics in 2014 for his contribution to the development of the light-emitting diode (LED), has died at the age of 92, according to local media.

Originally from

Minamikyushu

(southwestern Japan) and an electrical engineer by training, Akasaki served as a professor at

Nagoya University

and devoted much of his career to research and development in the field of semiconductors.

His work for decades in this area contributed to the use of an alloy known as

Gallium nitride

essential for the development of the light-emitting diode, a technology invented in the early 1990s capable of emitting bright light and saving energy.

The results of their investigations made possible the

LEDs

of primary colors red, green and blue, which expanded the practical applications of these diodes that today are used for example in television screens or in lighting systems.

That work was recognized with the award of the

Nobel Prize in Physics in 2014

, an award shared between Akasaki and fellow Japanese

Hiroshi Amano

and

Shuji Nakamura

, the latter a nationalized American.

The Swedish Academy decided to award the award to all three for their respective contributions to

LED

technology

.

Amano was a student of Akasaki and was part of his research group at Nagoya University, while Nakamaura worked on his own.

Akasaki's

work

was also recognized with other awards such as the Queen Elizabeth Award for Engineering, the Order of Culture of Japan or the IEEE Edison Medal.
