WebA novel hydrothermal layer-by-layer processing method for the fabrication of core/alloy nanoparticles with highly tunable surface plasmon resonance is described. For a model system of Au/Au(x)Ag(1-x), the processing temperature, alloy composition, and alloy thickness resulted in unique and tailorable plasmonic signatures. Web17. jan 2024 · Resonance structures are stabilizing in molecules because they allow electrons to lengthen their wavelengths and thereby lower their energy. This is the reason that benzene (C 6 H 6) has a lower heat of formation than organic chemists would predict, not accounting for resonance.
