- PublicationEffect of cavity architecture on the surface enhanced emission from site selective nanostructured cavity arrays(ACS Publications, 2012-03)
; ; ; ; Presented here are studies of the impact of incident angle on surface-enhanced emission from a dye that is located site selectively on a plasmon-active nanocavity array support. Studies were performed for a surface-active luminescent dye selectively assembled on the top surface or on the walls of the voids of nanocavity array substrates. Results show that emission intensities depend on where the dye is located with respect to the void or surface of the nanocavity array and on the dimensions of the cavity. This was interpreted to arise from the presence of void-localized plasmons and surface-localized and -delocalized plasmon modes.428Scopus© Citations 32 - PublicationSurface enhanced resonance Raman and luminescence on plasmon active nanostructured cavities(American Institute of Physics, 2010-10-11)
; ; ; ; Presented here are studies of the impact of excitation angle on surface enhanced Raman and luminescence spectroscopy of dye immobilized on a plasmon active nanocavity array support. Results show that both Raman and luminescence intensities depend on the angle of incidence consistent with the presence of cavity supported plasmon modes. Dependence of scattering or emission intensity with excitation angle occurs over the window of observation.303Scopus© Citations 29 - PublicationSite selective surface enhanced Raman on nanostructured cavities(American Institute of Physics, 2011-07-18)
; ; ; ; Presented here are angle dependence studies on the surface enhanced Raman (SER) signal obtained from dye placed on plasmon active nanocavity arrays. A comparative study was carried out between two modified array supports. One array had dye placed only on the interior walls of the cavities in the array. The other array had dye placed only on its top flat surface. Results show that Raman intensities as a function of angle depend on the location of the dye on the array; this was interpreted to arise from the presence of different plasmon polariton modes in these sites.343Scopus© Citations 30
