Quantum dots could be the light bulb’s successor

Abstract:
Take an LED that produces intense, blue light. Coat it with a thin layer of special microscopic beads called quantum dots. And you have what could become the successor to the venerable light bulb.

The resulting hybrid LED gives off a warm white light with a slightly yellow cast, similar to that of the incandescent lamp.
