TL;DR: Hot-electron-induced photodissociation of H2 was demonstrated on small Au nanoparticles supported on SiO2, and the rate of dissociation was found to be linearly dependent on illumination intensity with a wavelength dependence resembling the absorption spectrum of the plasmon of the AuNPs.

TL;DR: With conversion efficiencies similar to those of inorganic SHG crystals, these structures provide a promising approach for the design and fabrication of stable, synthetic second-order nonlinear optical materials tailored for specific wavelengths.

TL;DR: It is shown that coherent anti-Stokes Raman spectroscopy (CARS) can be used to obtain single-molecule detection sensitivity, by exploiting the unique light harvesting properties of plasmonic Fano resonances.

TL;DR: A structure supporting the coherent oscillation of two distinct Fano resonances within an individual plasmonic nanocluster is reported, showing how this coherence enhances the optical four-wave mixing process in comparison with other double-resonant plAsmonic clusters that lack this property.

TL;DR: A new ultrasensitive infrared antenna designed to bring surface-enhanced infrared absorption (SEIRA) spectroscopy into the few-molecule detection range is reported, which offers a new platform for analyzing the IR vibrations of minute quantities of molecules and lends insight into the ultimate limit of single-Molecule SEIRA detection.
