Sub-5 nm nanobowl gaps electrochemically templated by SiO2-coated Au nanoparticles as surface-enhanced Raman scattering hot spots.

چکیده
Large-area submonolayer and monolayer Au nanoparticle (NP) arrays with sub-5 nm nanobowl gaps for giant electromagnetic enhancement were created by partially embedding SiO2-coated Au NP arrays in an electrochemically deposited Au film, followed by the removal of the SiO2 shells.

Guided formation of sub-5 nm interstitial gaps between plasmonic nanodisks.
To achieve a reliable formation of a surface-enhanced Raman scattering (SERS) sensor with evenly distributed hot spots on a wafer scale substrate, we propose a hybrid approach combining physical nanolithography for preparing Au nanodisks and chemical Au reduction for growing them. During the chemical growth, the interstitial distance between the nanodisks decreased from 60 nm to sub-5 nm. The r...
متن کاملNanosphere arrays with controlled sub-10-nm gaps as surface-enhanced raman spectroscopy substrates.
We demonstrate a convenient and cost-effective chemical approach for fabricating highly ordered Au nanoparticle arrays with sub-10-nm interparticle gaps. Near-field enhancements inside the interparticle gaps create uniform periodic arrays of well-defined "hot spots" exploitable for large surface-enhanced Raman spectroscopy (SERS) enhancements. A cetyltrimethylammonium bromide (CTAB) bilayer sur...
متن کاملSurface-Enhanced Resonance Raman Scattering of Rhodamine 6G in Dispersions and on Films of Confeito-Like Au Nanoparticles
Surface-enhanced resonance Raman scattering (SERRS) of rhodamine 6G was measured on confeito-like Au nanoparticles (CAuNPs). The large CAuNPs (100 nm in diameter) in aqueous dispersion systems showed stronger enhancing effect (analytical enhancement factor: over 10⁵) of SERRS than the small CAuNPs (50 nm in diameter), while the spherical Au nanoparticles (20 nm in diameter) displayed rather wea...
متن کاملAlumina coated Ag nanocrystal monolayer as surface-enhanced Raman spectroscopy platforms for direct spectroscopic detection of water splitting reaction intermediates
A novel Ag-alumina hybrid SERS platform has been designed for the spectroscopic detection of surface reactions in steady state. Single crystalline and faceted silver (Ag) nanoparticles with strong light scattering were prepared in large quantity, which enables their reproducible self-assembly into large scale monolayers of Raman sensor arrays by Langmuir-Blodgett technique. The close packed sen...
متن کاملHighly Intensified Surface Enhanced Raman Scattering by Using Monolayer Graphene as the Nanospacer of Metal FilmMetal Nanoparticle Coupling System
An electromagnetic “hot spot” is a point with a strongly enhanced local fi eld which occurs near sharp asperities and also forms at the small gaps (nanometer or smaller) between metal nanostructures such as nanoparticles (NPs), NP-fi lm system, and. [ 1–12 ] In nanoparticle-fi lm-gap (NFG) system, metal NPs (supported localized surface plasmons LSPs) are separated from a bulk metal fi lm (suppo...
