We illustrate the important trade-off between far-field scattering effects, which have the potential to provide increased optical path length over broad bands, and parasitic absorption due to the excitation of localized surface plasmon resonances in metal nanoparticle arrays. Via detailed comparison of photocurrent enhancements given by Au, Ag and Al nanostructures on thin-film GaAs devices we ...

Voltage controlled wavelength tuning of the localized surface plasmon resonance of gold nanoparticles on an aluminum film is demonstrated in single particle microscopy and spectroscopy measurements. Anodization of the Al film after nanoparticle deposition forms an aluminum oxide spacer layer between the gold particles and the Al film, modifying the particle-substrate interaction. Darkfield micr...

Photocatalytic H2 Generation In article number 2000504, Hua Tang and co-workers designed a promising ternary photocatalyst CoO/TCN/Au heterostructure via integrating Au CoO nanoparticles with g-C3N4 hollow nanotubes. Localized surface plasmon resonance (LSPR) of promoted charge-carrier generation in g-C3N4, the appropriate band alignment between boosted hot electrons transfer from to which acti...
