“…In [18,[25][26], on the basis of studying the proper ties of a quantum model of the electron excitation energy transfer between the donor and acceptor mole cules located near the surface of a conductive nanocyl inder of infinite length, an increase in the transfer rate due to surface plasmons excitation in comparison with the absence of a conductive surface and the plasmon resonance conditions was discovered. In the quasi static approximation, the free plasma oscillations of the electrons in the nanowire lead to the origination of a surface charge, creating an electric field with a potential satisfying the Laplace equation.…”

“…Letokhov [4], a way to increase the spatial resolution of near field microscopes up to 1-100 nm using the phenomenon of the nonradiative donor-acceptor (DA) transfer of the electron excitation energy (Förster Resonance Energy Transfer (FRET)) through the small opening of a nanoneedle probe with the subsequent observa tion of the resonance fluorescence of the acceptor molecules on the surface of the investigated object [5][6][7] is proposed. It has been shown in a number of papers [8][9][10][11][12][13][14][15][16][17][18][19] that the characteristics of the resonance energy transfer between molecules can notably change near nanostructures, including the nanoneedle's end. It has been established through the efforts of a number of authors that nanobodies of the simplest shapes (nano spheres, nanocylinders, and nanocones) can signifi cantly increase the probability of the dipole or the pre viously forbidden quadrupole transition in compari son with the case of the free (without the outside objects participation) radiative transfer in the atom [20].…”

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.

“…In a number of theoretical and experimental works, FRET has been studied at the level of individual molecules and particles, or for certain (so-called " model") compounds [21,22]. However, for a wide class of compounds, this process is still poorly understood, and the number of articles devoted to the creation of model representations of plasmon-activated energy transfer between organic molecules is relatively small [23][24][25][26].…”

To explain the experimentally observed effect of silver nanoparticles on the fluorescence of organic dyes and the nonradiative intermolecular transfer of electronic excitation energy in multilayer nanostructures, the previously proposed theoretical model of plasmon resonance in spherical nanoparticles of metals was used. The rates of radiative and nonradiative (FRET) processes in film structures with Ag nanoparticles were calculated for fluorescein and rhodamine B molecules, as well as for two-component systems fluorescein-nile red (NR) and rhodamine B-NR. A version of the model was used that takes into account the effect of NPs on FRET between molecules, the radiative decay of donor and acceptor molecules, and the energy transfer from the dye to plasmonic nanoparticles. The calculation of the UDA rate for pairs with different energy transfer efficiency showed a greater increase in the UDA parameter for the fluorescein-nile red pair than for the rhodamine B-nile red pair. Estimation of the fluorescence enhancement factor of donor and energy acceptor molecules and the rate of energy transfer from the dye to silver NPs showed their insignificant contribution to the formation of the resulting energy transfer efficiency enhancement in the presence of plasmonic NPs.

The effect of multilayer nanoparticles consisting of a conducting spherical core and two shells, dielectric and metallic, on nonradiative energy transfer from organic luminophore molecules to acceptor molecules is studied. The dipole polarizability of the nanoparticle is examined with and without taking into account the degeneracy of the electron gas of the conducting components. The rate of transfer of the energy of electronic excitation between molecules near multilayer nanoparticles and the rate of transfer directly to the nanoparticles are calculated in the quasistatic (near fi eld) approximation of electrodynamics. Multilayer nanoparticles are found to have a signifi cant effect on the decay kinetics of excited singlet states of the donor molecules.Introduction. The optical properties of metallic nanostructures are of ongoing interest because they could serve as the basis of some nano-and molecular electronic devices [1]. Improvements in ultra-high resolution fl uorescence microscopes based on nonradiative transfer of energy from molecules on the tip of a needle to luminophore molecules on a test sample are of particular importance [2]. Here the effect of nanoparticles with different shapes and structures on the transfer of electronic excitation energy to donor-acceptor molecular pairs is of special interest. Resonant enhancement of the rate of energy transfer when the molecules are close to a conducting surface has been reported [3-9] when the emission and absorption spectra of the donor and acceptor molecules overlap with the plasmon spectrum of a nanostructure.In this paper, we consider a spherical multilayer nanoparticle consisting of a metallic core surrounded by two shells, dielectric and conducting. These kinds of structures are of interest because, for a certain geometry of the nanosystem, the scattering of light is increased by three orders of magnitude [10]. We have studied the quenching of electronically excited states of a luminophore molecule by this kind of nanoparticle, as well as the effect of the nanoparticle on the rate of energy transfer between nearby molecules. It should be noted that, to some approximation, this kind of structure can serve as a model for endometallofullerene complexes, and the effect of these systems on the luminescence of dyes has recently also been under active study.Dynamic Polarizability of Multilayer Nanostructures. Consider a symmetric composite nanostructure consisting of a conducting core and two adjoining concentric shells, one dielectric and the other metallic. We place it in the near fi eld of the oscillating dipole of a luminophore molecule; in a quasielectrostatic approximation this fi eld can be regarded as constant and uniform. Treating the electron gas in the metal as classical, we write the solution of the Laplace equation for the potential of the resultant fi eld φ(r, θ) in the form
