Quantum dots are extremely tiny nanoparticles typically between 10 to 10,000 atoms (1 to 9 nanometers) in diameter; they are thus smaller than 1/10,000th the width of human hair. Quantum dots are so small that they cannot be seen under a conventional microscope.   However, the effects of this extreme small size cannot be ignored. Quantum dots are actually very powerful materials, and their size gives them unique abilities, including highly efficient conversion of light to nearly any color in t...
