Quantum Dots

Caption

Each of these jars contains the same substance. The difference is the size of the particles. Quantum dots, suspended in liquid, absorb white light and then reemit it in a specific color that depends on the particle's size. Each quantum dot is about one ten-millionth of an inch in diameter and is composed of a few hundred atoms of material.
