LSPR of Nanoparticles Inside Strong Absorbent Medium In such sensors, the attenuation effects of the surrounding medium (absorbent medium AbsM) reduce the actual signal strength of the localized surface plasmon resonance (LSPR)
Localized surface plasmon resonance: Nanostructures . . . Nanostructures that support plasmons play a significant role in enabling surface enhanced techniques, such as surface enhanced Raman spectroscopy (SERS) and surface metal enhanced fluorescence (SEF or MEF)
Influence of aspect ratio and surrounding medium on Localized . . . The LSPR wavelengths are reported to be highly sensitive to the size, shape, and surrounding medium dielectric constant of the nanoparticle [2–5] A nanorod conducts two peaks in their LSPR spectrum, called transverse and longitudinal modes
Influence of surfactant, particle size and dispersion medium . . . In fact, energy dissipation within the particle is more likely for smaller size NPs (NPs having size smaller than the wavelength of light) compared to bigger NPs As the particle size increases, re-radiation of the energy by the particle to the surrounding medium is expected to be dominant
Effect of Size Distribution, Skewness and Roughness on the . . . It is shown that the mean particle size can be correctly estimated directly from the plasmon band position, as it is the mean that determines the resonance wavelength The standard deviation can on the other hand be estimated from the intensity distribution data obtained from dynamic light scattering experiments
