At the beginning of the 1980s, the first reports of surface-enhanced infrared spectroscopy
(SEIRS) surfaced. Probably due to signal-enhancement factors of only 101 to 103, which are …

Absorption, scattering, and fluorescence are processes that increase with electric field
intensity. The most prominent way to enhance electric field intensity is to use localized or …

Development of a novel, cost-effective, and highly efficient mid-infrared light source has
been identified as a major scientific and technological goal within the area of optical gas …

CaF2 seems to be the ideal substrate material for the infrared spectroscopy of organic and
biological layers, since its refractive index is very similar to that of these materials. As a …

Spectrally selective thermal emission is in high demand for thermophotovoltaics, radiative
cooling, and infrared sensing applications. Spectral control of the emissivity is historically …

Graphene plasmon with extremely strong light confinement and tunable resonance
frequency represents a promising surface-enhanced infrared absorption (SEIRA) sensing …

The thermal tunability of the optical and electrical properties of phase-change materials has
enabled the decades-old rewritable optical data storage and the recently commercialized …

Graphene, with its unique properties including atomic thickness, atomic uniformity, and
delocalized π bonds, has been reported as a promising alternative material versus noble …

Metal structures with resonances in the mid-infrared spectral range enable an increased
sensitivity for detecting molecular vibrational signals. 1D gold strip gratings have already …
