The History and Future of Quantum Dots
Quantum Dots (QDs), also known as semiconductor nanocrystals, are quasi-zero dimensional nanoparticles with the size between 2 and 10 nm.
- Quantum Dots (QDs), also known as semiconductor nanocrystals, are quasi-zero dimensional nanoparticles with the size between 2 and 10 nm.
- The dimensions of QDs are smaller than the Fermi wavelength of electrons inside of QDs materials, and the movement of electrons in all directions is limited, thus leading to a remarkable quantum confinement effect (QCE) or quantum size effect.
- Later, Prof. Peng, collaborated with NajingTech (Najing Technology, Hangzhou, China), first proposed a new application related to the electroluminescent QDs-based devices (quantum dots light-emitting diode, QLED), in addition to photoluminescent (PL).
- Quantum Dot Enhancement Film (QDEF) was first out from NajingTech, 3M and Nanosys, and has been already mounted into most of high-end TVs.
