“…Modern nanofabrication methodologies enable the creation of a number of different nanostructures with precisely controlled shapes, sizes, and spacings. [9][10][11][12][13][14] One particular area of active research within plasmonics is the investigation of the effect of nanostructure substrate geometry on the optical properties of materials in the near-field of the LSP. 4,5,7,8,15 Nanostructured metal dielectric interfaces in nanoscale thick metal films can couple light with LSP to produce a reflectance spectrum that is sensitive to changes in surface dielectrics.…”

In this paper we probe surface enhanced Raman scattering (SERS) and Surface enhanced Fluorescence (SEF) from probe molecule Rhodamine 6G (Rhod6G) on self-standing Au nanorod array substrates made using a combination of anodization and potentiostatic electrodeposition. The finished substrates were embedded within a porous alumina template. By varying the etching time i.e. the thickness of the alumina, we show that there exists an inverse relationship between SERS and SEF. SERS and SEF also show a nonlinear response to increasing etching time due to an inhomogeneous plasmon activity across the nanorod. By modeling the electromagnetic fields created at different etching times we confirm the nonuniform plasmon activity along the Au nanorods and explain the nonlinear behaviors of SERS and SEF. Optimization of the level of alumina matrix thickness optimizes conditions for obtaining either maximized SERS, SEF or for simultaneously observing both SERS and SEF together.

“…A considerable amount of research has been undertaken to advance the understanding of optical processes in molecular-or nano-materials such as quantum dots, nanodisks, fullerenes and carbon nanotubes [1][2][3][4][5][6][7][8][9]. Optical spectroscopy and microscopy techniques such as Raman and fluorescence based methods provide a way to potentially analyse both the optical and structural properties of such materials [2][3][4][5][6][7][8][9][10][11].…”

The Effect of Ag Nanoparticles on Surface-Enhanced Luminescence from Au Nanovoid Arrays

et al. 2013

Key wordsNanoparticles, gold nanovoid arrays, Raman, luminescence AbstractStudies comparing the effect of adding two different nanoparticles compositions on the plasmonic properties of Au nanovoid arrays were undertaken. Surface enhanced resonance luminescence and surface enhanced resonance Raman studies comparing dispersed Ag nanoparticles and Ag nanoparticle aggregates on gold nanovoid arrays were undertaken. These studies showed that using Ag nanoparticle aggregates increased the both luminescence and Raman efficiency relative to when dispersed nanoparticles were used, in addition these studies also showed that adding dispersed Ag nanoparticles supported a more reproducible enhancement in luminescence and Raman across the substrate compared to using Ag nanoparticle aggregates. Finite element analysis simulations indicated that surface plasmon polariton distribution in the sample was affected by the presence of the Ag nanoparticles on the Au nanovoid array.

Surface enhanced Raman scattering (SERS) from molecules absorbed onto plasmon active substrates is known to possess continuum emission profiles upon which Stokes Raman peaks are super-imposed. We study here the effect of temperature upon the continuum emission and Stokes Raman peak ratios from a monolayer of probe molecules prepared on a plamon active nanocavity array from an active spherical cap architecture nanomaterial substrate. Our results show that there is partial recover of SERS spectral profile following heating. This change is interpreted in terms of a molecular rearrangement of molecules on the substrates surface.
