  • This Review extends fluctuational electrodynamics, introduced originally to deal with radiation due to thermal fluctuations, to provide a unified quantitative theoretical framework that accounts for light emission processes in solids.

  • Quantum dots encapsulated in a gold nanoshell provide a hybrid plasmonic–fluorescent emitter with increased stability against high power excitation or drastic changes in the environment.

  • Sources of incandescence emit their radiation across a broad spectrum. The finding that metamaterials can be used to tune the sources' emission spectrum makes these emitters an attractive prospect for some applications.

  • Radiation transfer on the nanoscale across gaps varying between 30 nm and 2.5 µm is investigated experimentally. The enhancement of heat transfer by evanescent wave contributions may pave the way for the design of sub-micrometre nanoscale heaters and radiators.

  • Developing a microscale ultrafast electrical source of surface plasmons is crucial for nanophotonic applications. Here, the authors report the design, fabrication and characterization of nanoantennas for emission and control of surface plasmons by inelastic electron tunneling.

  • Far-field mid-infrared spectroscopy reveals both the electroluminescence of hyperbolic phonon polaritons of hexagonal boron nitride excited by strongly biased graphene, and the associated radiative energy transfer through the material.

  • In this work, the authors use a surface plasmonic mechanism to efficiently confine TeraHertz photons inside ultrasmall cavities. These plasmonic-based TeraHertz cavities are shown to operate until the ultimate limit that is allowed fundamentally and at which plasmons start to behave in a nonlocal fashion.

  • Nanoresonator is proven to be an excellent platform for molecular detection, yet a set of them is necessary to identify a molecule fingerprint. Here, the authors utilise low quality resonators with large radiative losses, despite its lower quality factor, to identify molecular absorption spectrum between 5 and 10 μm.
