From Popular Science: Why A Blue LED Is Worth A Nobel Prize; Plus, a little history of making semiconductors glow

Excerpt: "Three scientists have jointly earned the Nobel Prize in physics for their work on blue LEDs, or light-emitting diodes. Why blue in particular? Well, blue was the last -- and most difficult -- advance required to create white LED light. And with white LED light, companies are able to create smartphone and computer screens, as well as light bulbs that last longer and use less electricity than any bulb invented before."

From Geek.com: Blue light Nobel Prize has LED inventor seeing red

So, when year after year went by without an all-important Nobel nod to LEDs, some in the industry called foul — against Holonyak’s resistance. He says he long ago put aside any lingering hopes that he would win a Nobel, but never imagined that someone else might get it for the technology he himself invented."
