Optoplasmonic Effects in Highly Curved Surfaces for Catalysis, Photothermal Heating, and SERS

“…11 When a surface plasmon resonance is excited on a nanostructure, the electric field is highly concentrated in a nanometric volume, leading to a large enhancement of spectroscopic signals (e.g., surface-enhanced Raman scattering (SERS) 3 and luminescence 12,13 ) and generating hot electrons capable of catalyzing reactions. 9,10,14 A key research area in nanomaterials is the design of nanostructures that generate the large enhancement necessary to realize many nanoplasmonics applications. 15−17 In addition to the design of structures with stronger electric field confinement or sharper resonances, one can also improve the performance of plasmonic processes by more efficiently coupling light into, and in some cases collecting light from, the nanostructure, giving rise to the field of optoplasmonics, where photonic elements are combined with plasmonic nanostructures.…”

Bimetallic copper palladium nanorods: plasmonic properties and palladium content effects

“…33 However, dielectric function mixing is also occurring, such that the plasmonic properties of the bimetallic structure may suffer from the addition of a poor plasmonic metal such as Pd, in which interband transitions are signicant across the UV-Vis-NIR. 34 Despite the expected damping, plasmon resonances have been demonstrated in Au NPs containing Pd, 26,35 and subsequently alloying and decoration have been successful in imparting catalytic properties to plasmonic structures based on Au, 36,37 Ag, 38,39 Cu, [40][41][42] Al, 43,44 and Mg, 45 to name a few.…”
