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.
