Abstract Localized 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.

Localized surface plasmon resonance (LSPR) is one of the signature optical properties of noble metal nanoparticles. Since the LSPR wavelength λ max is extremely sensitive to the local environment, it allows us to develop nanoparticle-based LSPR chemical and biological sensors. In this work, we tuned the LSPR peaks of Ag nanotriangles and explored the wavelength-dependent LSPR shift upon the adsorption of some resonant molecules. Localized surface plasmon resonance (LSPR) in semiconductor nanocrystals (NCs) that results in resonant absorption, scattering, and near field enhancement around the NC can be tuned across a wide optical spectral range from visible to far-infrared by synthetically varying doping level, and post synthetically via chemical oxidation and reduction, photochemical control, and electrochemical control. Nowadays, one of the most extensively exploited features of metallic NPs is the localized surface plasmon resonance (LSPR), which refers to the collective oscillation of electrons on the metallic LSPR : localized surface plasmon resonance Localized surface plasmon: a photon-driven coherent oscillation of the surface conduction electrons in a material with negative real and near-zero imaginary dielectric constant SERS : surface-enhanced Raman scattering INTRODUCTION Materials that possess a negative real and small positive imaginary dielectric constant are capable of supporting a surface plasmon resonance (SPR). Localized surface plasmon resonance (LSPR) of a noble metal nanoparticle (NP) can also be used for sensing due to a shift of its resonant wavelength in response to a refractive index change.

Localized surface plasmon resonance (LSPR) of a noble metal nanoparticle (NP) can also be used for sensing due to a shift of its resonant wavelength in response to a refractive index change. 1,2 Since a LSPR sensor simply measures an extinction (=absorption + scattering) peak shift or just an extinction change , it requires a simple optical configuration without a prism and it is cost-effective and suitable for miniaturization. 3 It would therefore facilitate real-time and on-site medical Localized surface plasmon resonance (LSPR) is shown to be effective in trapping light for enhanced light absorption and hence performance in photonic and optoelectronic devices. Implementation of LSPR in all‐inorganic perovskite nanocrystals (PNCs) is particularly important considering their unique advantages in optoelectronics. Localized surface plasmon resonances (LSPRs) typically arise in nanostructures of noble metals 1, 2 resulting in enhanced and geometrically tunable absorption and scattering resonances. LSPRs, WN Coupled with Bi Nanoparticles to Enhance the Localized Surface Plasmon Resonance Effect for Photocatalytic Hydrogen Evolution Jingxuan Hao Shanghai Key Laboratory of Materials Protection and Advanced Materials in Electric Power, Shanghai Engineering Research Center of Energy-Saving in Heat Exchange Systems, Shanghai University of Electric One of the most explored characteristics of the noble metal nanoparticles (essentially silver, gold or copper) is the localized surface plasmon resonance (LSPR), which is the frequency at which conduction electrons collectively oscillate in response to the alternating electric field of an incident electromagnetic radiation.

Moreover, the LSPR is responsible for the electromagnetic-field enhancement that leads to surface-enhanced Raman scattering (SERS) and other surface-enhanced spectroscopic processes. Localized surface plasmon resonance (LSPR) has emerged as a leader among label-free biosensing techniques in that it offers sensitive, robust, and facile detection. Traditional LSPR-based biosensing utilizes the sensitivity of the plasmon frequency to changes in local index of refraction at the nanoparticle surface.
