“…The blue shift in surface plasmon resonance with the reduction in the particle size can fully be explained by the quantum sphere model (QSD), which considers the enlargement of energy splitting as the particle size is decreased [32]. Small particles prepared by sol-gel process usually assume a spherical shape under surface tension.…”

“…The theory of this topic has a long history starting with Kubo [79] who was the first to explore in detail how thermodynamic properties will be modified by the discrete energy level in small metal NPs (MNPs). This inspired many similar 'particle in a box' type models [29], [51], [63], [89], [110], [123], [143], [151]. In particular Rice et al [123] were the first to perform a calculation of the polarizability of small particles that took electron screening into account.…”

Quantum plasmonics is an exciting sub-branch of nanoplasmonics where the laws of quantum theory are used to describe light-matter interactions on the nanoscale. Plasmonic materials allow extreme sub-diffraction confinement of (quantum or classical) light to regions so small that the quantization of both light and matter may be necessary for an accurate description. State of the art experiments now allow us to probe these regimes and push existing theories to the limits which opens up the possibilities of exploring the nature of many-body collective oscillations as well as developing new plasmonic devices, that use the particle quality of light and the wave quality of matter, and have a wealth of potential applications in sensing, lasing and quantum computing. This merging of fundamental condensed matter theory with application-rich electromagnetism (and a splash of quantum optics thrown in) gives rise to a fascinating area of modern physics that is still very much in its infancy. In this review we discuss and compare the keys models and experiments used to explore how the quantum nature of electrons impacts plasmonics in the context of quantum size corrections of localised plasmons and quantum tunnelling between nanoparticle dimers. We also look at some of the remarkable experiments that are revealing the quantum nature of surface plasmon polaritons.

“…w ∝1/R, as obtained from Equations (15) and (16), results from the changing mean free path of the electrons. Figure (4) gives a comparison between the experimentally measured absorption band for silver particles of about 10 nm diameter, suspended in glass, and the calculated one from Equation (14), using the measured λ m and bandwidth [18]. The agreement between these curves confirms that the absorption results from the free electrons in the silver particles.…”
