About this Research Topic
The field of nanoplasmonics deals with the study of the electromagnetic phenomena in the nanoscale vicinity of metal surfaces. Although it may sound strange to common sense, the awareness of the resonant properties of plasmonic metal nanoparticles is readily apparent to the naked eye. Because the nanoparticles absorb and scatter visible light, they can generate a wide palette of colors, depending on their concentration, geometries, and dimensions. These optical effects have been used since antiquity (e.g. in Roman glasses and stained-glass windows of medieval cathedrals) and have inspired several practical uses in different scientific and technological areas. The physical interpretation of plasmonic effects only started to gain relevance at the beginning of the 20th century with the theory proposed by Gustav Mie, who deduced a solution of Maxwell's equations to calculate the extinction spectrum of a metallic nanoparticle in the quasi-static condition. Yet, only in the 1950s, it was experimentally demonstrated the existence of self-sustained collective excitations at metal surfaces, which were named thereafter as surface plasmons. About two decades later, in 1974, it was reported for the first time the phenomenon of surface-enhanced Raman scattering (SERS).
In the last few decades, there have been significant advances in both theoretical and experimental investigations of surface plasmons, which led to the development of new simulation methods to calculate the optical properties of nanoplasmonic systems and has delivered a relevant number of important applications.
This Research Topic focuses on the latest advances and most exciting results in the area of Nanoplasmonic Thin Films, i.e. materials containing plasmonic nanoparticles used to enhance several light-matter interaction processes (Raman scattering, photocatalysis, chemical energy conversion, heat generation, photovoltaics, etc.), to accurately detect different kinds of molecules and biomolecules using label-free sensing platforms, or even to perform biological imaging and photothermal therapies.
We welcome contributions reporting new knowledge and/or breakthrough innovations in the development of nanoplasmonic thin films, addressing radical new design concepts that can be supported by theory, and new thin film deposition pathways to fabricate these materials, ranging from physical vapor deposition (PVD) to chemical vapor deposition (CVD) techniques, or nanolithography methods.
