Crystalline nanoparticle that exhibits size-dependent properties due to quantum confinement effects on the electronic states
Reference : ISO/TS 27687:2008
A quantum dot is a nanocrystal made of semiconductor materials that are small enough to exhibit quantum mechanical properties.
Reference : Chemistry and Physics of Semiconductor Nanocrystals
Nanoparticle or region which exhibits quantum confinement in all three spatial directions. Quantum confinement means restriction of a particle’s motion in one, two or three space dimensions when the size of a physical system is of the same order of magnitude as the particle’s de Broglie’s wavelength
