Luminescent nanomaterials

nanomaterial; nanomaterial

Material with at least one dimension smaller than 100 nm and whose properties are modified as a result.

luminescence; luminescence

Light emission resulting from the de-excitation of a charged particle (electron or hole).

CIGS; Copper Indium Gallium Selenide

Semiconductor alloy with the chemical formula Culn_xGa_(1-x)Se₂. Its energy band gap can be varied from 1 eV to &, 7 eV depending on the value of x.

Down conversion ; down conversion

Emission of photons with lower energies and therefore longer wavelengths than the photons used for excitation. The emission in question may be the result of simple radiative relaxation or an energy transfer phenomenon.

Quantum Cutting ; quantum cutting

Interaction of a photon with a medium in which it is transformed into two photons of equal...
