12 Jan 2017 In comparison with depolarized DLS, the method allows one to avoid measurement of the very weak cross-polarized component of the scattered light, and gives more data for solving the inverse (5-7) Depolarized dynamic light scattering (DLS) is a known sizing technique for nonspherical nanoparticles.

6 Jun 2014 Small particles with surface plasmons can be used to detect the fluorescence of single molecules, enhance Raman scattering, resonantly transfer energy of We begin with a review of the classical light scattering theory for spherical particles based on the quasistatic (Rayleigh) approximation and the
a structured cylindrical waveguide, further enhancing sensitivity. . waveguides [7] can in principle also be integrated into conventional structured optical fibres. . Dynamic light scattering (DLS) measurements and transmission electronic microscopy (TEM) images confirmed that uniform TiO2 nanoparticles on the order of
Here we describe a dynamic light scattering experiment where the evanescent part of waveguide modes is used as the source of light. Using waveguide modes increased the signal-to-noise ratio by a factor of 8 compared to evanescent waves generated by total internal reflection and it allows adjusting the spatial resolution
21 Dec 2010 Here we describe a dynamic light scattering experiment where the evanescent part of waveguide modes is used as the source of light. Using waveguide Dynamic light scattering is a very powerful method to characterize the dynamics of polymers and nanoparticles in bulk solution. In pure homodyne
19 Dec 2017 Request (PDF) | Resonance enhanced d | We present a novel light scattering setup that enables probing of dynamics near solid surfaces. An evanescent wave generated by a surface plasmon resonance in a metal layer is the incident light field in the dynamic light scattering experiment. The combination
The limitation to use a noble metal as the interface in REDLS is relieved in the evanescent scattering method Waveguide Enhanced Dynamic Light Scattering (WEDLS) by using a thick layer of a transparent material as PMMA on top of the typically 50 nm gold layer on the prism. Waveguides are excited at specific angles,
15 Aug 2014 One of the most promising applications of SPPs, especially localized SPPs, is surface-enhanced Raman scattering (SERS), which has been studied both theoretically and . The polarization dependence of incident light in a plasmonic waveguide has also been studied for both Ag and Au nanowires.
