Fluorescent semiconductor nanocrystals: nanoparticles for multiple applications

Quantum confinement effect; quantum confinement effect

Discrediting the energy levels of a semiconductor and increasing its band gap as a result of reducing at least one of its dimensions below the exciton's Bohr radius.

Bohr radius of the exciton; exciton Bohr radius

Average distance between electron and hole in an exciton (electron-hole pair), calculated with Bohr's "planetary" model of the hydrogen atom.

Fluorescence; fluorescence

Emission of photons with energy corresponding to the nanocrystal gap, caused by absorption of higher-energy photons.

fluorescence quantum yield; fluorescence quantum yield

Specifies the emission efficiency, defined as the ratio of the number of photons emitted to the number of photons absorbed by the sample.

power conversion efficiency of a solar cell; Rendement de conversion énergétique d'une cellule solaire
