Plasmonics
Like a night sky: Gold nanoparticles observed with a dark field optical microscope
Plamonics is a scientific topic at the edge of optics and condensed matter physics. It deals with collective modes of electrons associated with an electromagnetic wave generated at the interface between a metal and an insulator. For example a plasmon wave at the surface of gold surface is called Surface Plasmon Polariton (SPP). Plasmons can also originate from a metallic nanoparticle (size between 5 and 100 nm approximately) and is called Localized Surface Plasmon Resonance (LSPR).
Plasmonique et nano-optique
La plasmonique est une discipline à la frontière entre l’optique et la physique de la matière condensée. Elle s’intéresse aux oscillations collectives d’électrons associées à une onde lumineuse. Concrètement l’onde plasmon apparaît à l’interface entre un métal et un isolant comme par exemple à la surface d’un film d’or, et on parle alors de plasmon propagatif ou SPP (Surface Plasmon Polariton). L’onde plasmon prend une forme différente, appelée plasmon localisé, LSPR (Localized Surface Plasmon Resonance) dans des nanoparticules quand leur taille est bien inférieure à la longueur d’onde, c’est-à-dire entre 10 et 100 nm (excitation par de la lumière visible).
