“…Although the dipole-type optical emitter is nonpolarized, the coupled field targeting the detector in Figure 10(b) is highly polarized in the TM [29]. This occurs because part of the CSNps emission is naturally in the TM polarization and can excite the SPP wave on the airgold interface, which evanescent wave passes through the thin metallic layer and radiate in the prism as a propagating wave polarized in the TM polarization.…”

The influence of a dielectric shell on metallic spherical nanoparticles [core-shell nanoparticles (CSNps)] in the resonant modal response of a surface plasmon resonance (SPR)-type sensor is presented. The planar multilayer sensor structure, based on the Kretschmann and surface plasmon coupled emission (SPCE) configurations, is coupled to a periodic array of these nanoparticles. In the first configuration, the CSNps are considered as a homogeneous layer with effective permittivity given by the Clausius-Mossotti mixing formula and polarizability of a core shell for a quasi-static scattering regime. In the second configuration, it performed an evaluation via the discrete complex image method (DCIM). Electromagnetic wave propagation is evaluated by the generalized reflection coefficient for multilayer structures. The analytical results are validated by numerical simulations performed via finite element method and also by experimental data. We observed that the dielectric shell thickness affects considerably the sensibility of the sensor when analyzing the change in other parameters of the CSNps array.Resonance 186

“…This system is located on the surface of TiO 2 films in the DSSC because of their higher molar extinction coefficients (100,000-300,000 M ¡1 cm ¡1 ) than ruthenium-based complexes (low molar extinction coefficients (5000-20,000 M ¡1 cm ¡1 )) [29]. In order to prepare samples with proper concentrations of rhodamine and squarylium dye, the F€ orster critical distance and critical concentration (Supporting Table 1) were calculated to be 2.9 nm and 10 ¡2 M based on the spectral measurement data [30,31]. The critical distance between these two dyes was determined to be 2.9 nm, which is in the range of the values of purple bacteria [16].…”

This study focuses on understanding the fundamentals of energy transfer and electron transport in photovoltaic devices with uniquely designed nanostructures by analysing energy transfer in purple photosynthetic bacteria using dye-sensitised solar cell systems. F€ orster resonance energy transfer between the xanthene dye (donor of energy) and a new polymethine dye (acceptor of energy) was studied in dye-sensitised solar cells, which leads to a doubling of energy conversion efficiency in comparison to the cell with only the polymethine dye. The electron transport in the two different nanostructures of zinc oxide (nanorods and nanosheets) was investigated by spectroscopic methods (UV-vis spectrometer, time-resolved photoluminescence spectroscopy) and electrochemical potentiostat methods. The nanosheet structure of zinc oxide showed high short circuit current and long diffusion length. This fundamental study will lead to efficient artificial photosystem designs.

“…For instance, in the paper [30], energy transfer in a pair of molecules of rhodamine 110 (iodide of diethyltiacyanide on a silver base with the participation of surface plasmons) was investigated. The authors report an increase in the energy transfer rate in this system in comparison with the "plasmon less" case.…”

The problem of increasing the quality of the image created by a scanning near field optical micro scope with the Förster Resonance Energy Transfer (FRET) module is discussed. The possibility of improving the resolution of the near field optical microscope due to the FRET effect is analyzed, as is the formation of high quality images of nanoobjects on the basis of signals of increased intensity obtained by means of plas mon resonance in specially formed metal nanostructures (the plasmon resonance antennas). Research results for the nonradiative transfer of the electron exitation energy between the molecules placed near the planar surface of a conductor or a metal nanocylinder of the nanometer radius, as well as around a spherical nano particle, are presented. In the simplest model, the influence of the conducting phase boundary is taken into account by introducing an effective dipole image. If the antenna is a sphertical nanoparticle, then multipole polarization formalism is a more adequate representation of the responce.
