GLOSSAIRE DE LA PHOTONIQUE

Définition

L’absorption de photons, ou simplement l’absorption, est le processus par lequel l’énergie lumineuse est absorbée par un matériau, la transformant en énergie interne (par exemple, en énergie thermique) excitant des électrons à des niveaux d’énergie supérieure, ou générant des porteurs de charges libres dans le cas des semi-conducteurs. L’absorption entraîne l’atténuation de la lumière incidente.

Français

Absorption de photons

Anglais

Photon absorption

Photon absorption or simply absorption is the process by which light energy is taken by a material, transforming it to an internal energy of the media (e.g., thermal energy) or even generating electrons as in the case of semiconductor property. Absorption results in the attenuation of the incident light.
