Localized surface plasmon resonance: nano-sinusoid arrays [PDF]
Journal of Electromagnetic Waves and Applications, 2013 A new nano-sinusoid shape has recently been proposed, which offers the advantage of more resonance wavelength tunability than that offered by other sharp-tip nano-particles. In this paper, a one-dimensional (1D) chain of the nano-sinusoids is modelled, and results are compared with those describing chains of nano-triangles and nano-diamonds.

Localized Surface Plasmon Resonances of Anisotropic Semiconductor Nanocrystals
Journal of the American Chemical Society, 2011We demonstrate that anisotropic semiconductor nanocrystals display localized surface plasmon resonances that are dependent on the nanocrystal shape and cover a broad spectral region in the near-IR wavelengths. In-plane and out-of-plane dipolar resonances were observed for colloidal dispersions of Cu(2-x)S nanodisks, and the wavelengths of these ...

Localized Surface Plasmon Resonances
2017Surface plasmon polaritons are propagating energy waves at a plane metallic–dielectric interface. Metallic nanoparticles supply an effective restoring force to drive electrons in an oscillating electromagnetic field. A specific resonance condition leads to a field amplification localized in the near zone inside and outside the particle.

Localized Surface Plasmon Resonances for Sensing Applicaions
Advanced Photonics, 2014Using a rigorous electromagnetic method based on a curvilinear transformation of the coordinate system, we demonstrate the role of localized surface plasmon resonances on deep two-dimensional metallic gratings in enhancing the sensibility of optical sensing of several nanometer thin layers deposited on the grating surface.

Localized surface plasmon resonance of nanoporous gold
Applied Physics Letters, 2011We report the plasmonic properties of free-standing nanoporous gold (NPG) films with an intricate bicontinuous nanostructure. Two characteristic plasmon bands of NPG have been detected in absorption spectra. One at ∼490 nm, resulting from the resonant absorption of gold films, is independent of nanopore sizes and dielectric surroundings.

Exposed-core localized surface plasmon resonance biosensor
Journal of the Optical Society of America B, 2019We propose and numerically characterize an exposed-core photonic crystal fiber for biosensing applications. Surface plasmons are excited within gold (Au) strips, and titanium dioxide is employed to support adhesion of Au with glass. In consideration of ease of fabrication, only four air holes are used to simplify the sensor structure.

Nanometrology using localized surface plasmon resonance spectroscopy
2013 Conference on Lasers & Electro-Optics Europe & International Quantum Electronics Conference CLEO EUROPE/IQEC, 2013A novel optical characterization technique called localized surface plasmon resonance (LSPR) spectroscopy is presented. LSPR spectroscopy exploits light excited surface plasmons, which are collective coherent electron oscillations at a metal/dielectric interface.
