- PublicationThe Effect of Ag Nanoparticles on Surface-Enhanced Luminescence from Au Nanovoid Arrays(Springer, 2013-12)
; ; ; ; ; ; Studies comparing the effect of adding two different nanoparticle 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 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.Scopus© Citations 24 456 - PublicationTemperature dependence of a1 and b2 type modes in the surface enhanced Raman from 4-Aminobenzenethiol(Elsevier, 2013-01-29)
; ; ; ; ; ; ; We study here the effect of temperature upon the continuum emission and Stokes Raman peak ratios from a monolayer of 4-Aminobenzenethiol 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. Our results show that chemical enhanced b2-type modes are affected differently relative to electromagnetic enhanced a1-type modes and to the continuum emission background.Scopus© Citations 8 489
