What is a Quantum Dot? - dummiesA quantum dot is a nanoparticle made of any semiconductor material such as silicon, cadmium selenide, cadmium sulfide, or indium arsenide. Quantum dots may be able to increase the efficiency of solar cells. In normal solar cells, a photon of light generates one electron. Experiments with both silicon quantum dots and lead sulfide quantum dots can generate two electrons for a single photon of light.

Nanosys The Quantum Dot CompanyWhen a Quantum Dot absorbs a photon, it generates an electron-hole pair that recombines to emit a new photon. Crucially, the color of this emitted photon depends on the size of the quantum dot: Bigger dots emit longer wavelengths, close to red (620 to 750 nm); smaller dots emit shorter wavelengths, closer to the violet end (380 to 450 nm) of quantum dotsWhat is QLED?
