A quantum dot is a semiconductor nanostructure that confines the motion of conduction band electrons, valence band holes, or excitons (bound pairs of conduction band electrons and valence band holes) ...
Excitons, a bound state of an electron and an electron hole, can form when a given material absorbs a photon above its bandgap energy. The photon excites an electron from the valence band into the ...
