SURFACE PLASMON POLARITON LOCALIZATION
Surface Review and Letters, 2008Localization of surface plasmons polariton is reviewed in the context of experiments and modeling of near-field optical images. Near-field imaging of elastic (in-plane) surface plasmon scattering is discussed, and approaches for the correct image interpretation are outlined.

Localized Surface Plasmon Resonances in Aluminum Nanodisks
Nano Letters, 2008The plasmonic properties of arrays of supported Al nanodisks, fabricated by hole-mask colloidal lithography (HCL), are analyzed for the disk diameter range 61-492 nm at a constant disk height of 20 nm. Strong and well-defined (UV-vis-NIR) localized surface plasmon resonances are found and experimentally characterized with respect to spectral peak ...

Selective amplification of spoof localized surface plasmons
Applied Optics, 2019Here, selective amplification of spoof localized surface plasmons (LSPs) has been demonstrated, where two coupling stubs gathering energies from the spoof LSPs resonator are designed on the back of the corrugated metal-insulator-metal ring resonator. The quadrupole mode is selected and amplified through the coupling stubs and the incorporated amplifier

Localized Surface Plasmon Resonance Spectroscopy and Sensing
Annual Review of Physical Chemistry, 2007Localized surface plasmon resonance (LSPR) spectroscopy of metallic nanoparticles is a powerful technique for chemical and biological sensing experiments. Moreover, the LSPR is responsible for the electromagnetic-field enhancement that leads to surface-enhanced Raman scattering (SERS) and other surface-enhanced spectroscopic processes.

Potential-Scanning Localized Surface Plasmon Resonance Sensor
ACS Nano, 2015Localized surface plasmon resonance (LSPR) sensors based on plasmonic nanoparticles attract much attention recently. Here we propose a new class of LSPR sensor, that is, a potential-scanning LSPR sensor, in which electron density of the plasmonic nanoparticles is controlled by potential scanning.

Localized surface plasmon sensing platform
SPIE Proceedings, 2007Surface plasmon resonance (SPR) biosensors based on attenuated total reflection (ATR) have been widely used in biochemistry and genetic engineering, because it is a sensitive and label-free method. The dimension of the sensing probe is millimeters or more, so that the required amount of a sample solution is more than 100 μL even if a micro chamber ...

Sensitive Localized Surface Plasmon Resonance Multiplexing Protocols
Analytical Chemistry, 2012Herein are reported two new protocols to obtain different zones of localized surface plasmon resonance (LSPR) gold nanostructures on single glass substrate by using a vacuum evaporation technique followed by a high-temperature annealing (550 °C). The thickness of the gold film, considered as the essential parameter to determine specific LSPR properties,

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.

Surface-Dependent Localized Surface Plasmon Resonances in CuS Nanodisks
ACS Applied Materials & Interfaces, 2013We demonstrated revertible shifts of surface-dependent localized surface plasmon resonances (LSPRs) in CuS nanodisks. Oleylamine (OYA) served as a solvent and surface ligand covering on CuS nanodisks during the thermolysis of single-source precursor copper ethylxanthate (Cu(ex)2).
