Metallic nanostructures with nanometer gaps support hybrid plasmonic modes with an
extremely small mode volume and strong local field intensity, which constitutes an attractive …

Plasmonic photocatalysis enables innovation by harnessing photonic energy across a broad
swathe of the solar spectrum to drive chemical reactions. This review provides a …

The goal of this paper is to introduce a local form of Kirchhoff law to model light emission by
nonequilibrium bodies. While absorption by a finite-size body is usually described using the …

As one of the most important semiconductors, silicon has been used to fabricate electronic
devices, waveguides, detectors, solar cells, etc. However, the indirect bandgap and low …

The mechanism by which light is emitted from plasmonic metals such as gold and silver has
been contentious, particularly at photon energies below direct interband transitions. Using …

Photoluminescence from metal nanostructures following intense ultrashort illumination is a
fundamental aspect of light–matter interactions. Surprisingly, many of its basic …

The low quantum efficiency of silicon (Si) has been a long-standing challenge for scientists.
Although improvement of quantum efficiency has been achieved in porous Si or Si quantum …

The origin of light emission from plasmonic nanoparticles has been strongly debated lately.
It is present as the background of surface-enhanced Raman scattering and, despite the low …

Ultrasensitive surface-enhanced Raman spectroscopy (SERS) still faces difficulties in
quantitative analysis because of its susceptibility to local optical field variations at plasmonic …

Plasmonic antennas are well-known and extremely powerful platforms for optical
spectroscopy, sensing, and manipulation of molecules and nanoparticles. However …
