Summary

Surface plasmons are remarkable phenomenons that occur in metallic nanoparticles. This phenomenon consists on a collective oscillation of the conduction electrons being lighted by the appropriate wavelength which concentrates the electric field of the light in the environment of the nanoparticle and amplifying various orders of magnitude. Thereby, surface plasmons confer some optical properties on nanoparticles that are difficult to obtain with traditional optical such as semiconductors fluorescent molecules or pigments. Besides, they can be used to enhance the properties of other materials.

This lecture will describe in a summarized way the principles of surface plasmons, their possible applications in diverse fields such as medicine, energy, environment and technology as well as future challenges to process materials that use surface plasmons in functional nanomaterials.
