In the last century, molecular crystals functioned predominantly as a means for determining
the molecular structures via X-ray diffraction, albeit as the century came to a close the …

Optically variable devices (OVDs) are in tremendous demand as optical indicators against
the increasing threat of counterfeiting. Conventional OVDs are exposed to the danger of …

Driven by applications in chemical sensing, biological imaging and material
characterisation, Raman spectroscopies are attracting growing interest from a variety of …

In undergraduate courses on classical electromagnetism, it is taught that a perfect conductor
expels the electromagnetic (EM) field, and hence its surface is not able to support the …

Ultrathin dielectric gaps between metals can trap plasmonic optical modes with surprisingly
low loss and with volumes below 1 nm3. We review the origin and subtle properties of these …

Ten years ago, three teams experimentally demonstrated the first spasers, or plasmonic
nanolasers, after the spaser concept was first proposed theoretically in 2003. An overview of …

The excitation of surface plasmons (SPs)—collective oscillation of conduction-band
electrons in nanostructures—can afford photon, electron and heat energy redistribution over …

The properties of propagating surface plasmon polaritons (SPPs) along one-dimensional
metal structures have been investigated for more than 10 years and are now well …

Quantum plasmonics is a rapidly growing field of research that involves the study of the
quantum properties of light and its interaction with matter at the nanoscale. Here, surface …
