In physics, a plasmon is a quantum of plasma oscillation. Just as light (an optical oscillation) consists of photons, the plasma oscillation consists of plasmons.

Plasmonics describes the nanoscale (billionth of a meter) manipulation of optical signals at metal-dielectric interfaces. Inspired by photonics, plasmonics exploits the distinctive properties of …

There are however many reasons, why understanding the physics of plasmons is important to SERS. Firstly, plasmon resonances (in fact a certain type of plasmon resonance) are ‘what …

Plasmonics (or nanoplasmonics) is a young topic of research, which is part of nanophotonics and nano-optics. Plasmonics concerns to the investigation of electron oscillations in metallic …

The term plasmon defines a quasiparticle, or excitation mode, involving the free electrons of the material. Strictly speaking, the excitations involved in plasmonic studies are most often …

A plasmon can be defined as the quantum of plasma oscillations, from the point of view of quantum physics, or as the electromagnetic field produced by the collective oscillations of the …

1. Plasmons A plasmon is defined as a quantum of collective electron oscillation in a solid. It is also referred as a bulk plasmon (Figure 1 a). It may reveal itself in metals, doped …

A plasmon is the quantum energy content of any longitudinal wave (disturbance or vibration) that is moving through the crystal lattice via electron carriers and electron holes. The primary …

Plasmonics is a pivotal area within nanophotonics, a broader field that explores the manipulation and study of light on the nanometer scale. Nanophotonics encompasses a wide range of …

Plasmonics typically utilizes surface plasmon polaritons (SPPs), [2] that are coherent electron oscillations travelling together with an electromagnetic wave along the interface between a …
