Colloidal semi-conductor nanocrystals are made of small quantum dots, which are tiny
semiconductor nanostructures. A quantum dot contains a small number (on the order of
1-100) of conduction band electrons, valence band holes, or excitons. It is made of silicon,
cadmium, selenide, cadmium sulfide, or indium arsenide. It can be as small as 2 to 10
nanometers, corresponding to 10 to 50 atoms in diameter.
