Nobel Prize 2014: Out of the Blue

This year’s physics prize has been awarded to three scientists responsible for developing blue LED diodes.

The winners of the 2014 Nobel Prize in Physics are: Isamu Akasaki (Japanese, Meijo University/Nagoya University, Nagoya, Japan), Hiroshi Amano (Japanese, Nagoya University, Nagoya, Japan) and Shuji Nakamura (American, University of California, Santa Barbara, USA). The Royal Swedish Academy of Sciences awarded the prize

“for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources”

The invention of blue LEDs 20 years ago had a big impact on human lives. Before the three Japanese born scientists’ research there were only green and red LEDs available. These however were not able to create white light which is necessary for implementing mass lighting technologies. With the trio’s blue LEDs it was finally possible to create white light LEDs which are a lot more efficient and environment-friendly than the methods that were available before and can also be used for public lighting in cities and other places. The Royal Swedish Academy of Sciences now honoured this revolutionary innovation by bestowing Akasaki, Amano and Nakamura with the most well regarded title in science.

Optics in general is thought by many experts to be one of the driving forces in future technological advancement. The UNESCO even declared 2015 to be “The International Year of Light”.

Regardless of what awaits us in the future, with dedicated and passionate scientists like Akasaki, Amano and Nakamura unravelling ist mysteries it surely will be bright.
