The 2014 Nobel Prize in Physics went to three scientists and engineers, Profs Isamu AKASAKI, Hiroshi AMANO, and Shuji NAKAMURA for their invention of energy-efficient and environment-friendly blue light-emitting diode (LED). A natural question from readers might be, “Why blue in particular, but not LEDs in other colors?”
