It's nice to see when Nobel Prezes are given to the right people for the right reasons.

Seconded that. Most people wouldn't have had so much free ability to move around without the tension of energy being spent without the discovery of LEDs. Also, smart LED's will be used to power the streets of various cities when smart city modules come out.

This headline took me down memory lane. I was a cub reporter on EBN in the early 1990s (I say dating myself) and one of my very first page one stories was about commercial availabilities of blue LEDs. At the time, it was important because of signage issues and wanting to make a variety of colors in the signs. I have to admit i didn't forsee the importance of it at the time.

The Blue LED that can make white light

The importance this discovery has major impact on the lighting industry.

 

Alongwith RED and GREEN LEDS the BLUE LED completes the basic color set using which White light can be generated and such white light based illumination systems can replace today's Fluoresecnt Bulbs and tubes , resulting in huge energy savings and having longer life expectancy.

Is blue particularly challenging because of its short wavelength?

@Ariella, blue is challenging. if i remember correctly it was about finding a material the emits the right light spectrum. The early ones (back in 1989) were based on silicon carbide which was hideously inefficient. This new generation was made with gallium nitride, but its hard to make that compound bright.  Blue is critically important because you need blue to get white.

@Hailey very interesting!
