Coherent cooperative fluorescence resonance energy transfer

Serguei Sekatski

Cooperative fluorescence resonance energy transfer effect is experimentally demonstrated for a few crystals doped with rare-earth ions. We show that, at the liquid helium temperatures in similar crystals, coherent cooperative fluorescence resonance energy ...

Photonic Crystal Biosensor Based on Optical Surface Waves

Giovanni Dietler, Serguei Sekatski, Tatyana Karakouz

A label-free biosensor device based on registration of photonic crystal surface waves is described. Angular interrogation of the optical surface wave resonance is used to detect changes in the thickness of an adsorbed layer, while an additional simultaneou ...

Luminescence studies on photostimulable phosphor CsBr:Eu2+

Giovanni Dietler, Serguei Sekatski, Kanat Dukenbayev

Photostimulable phosphor CsBr:Eu2+ is prepared through a solid-state reaction. The effect of annealing atmosphere on photoluminescence and photostimulated luminescence was investigated. Optimum luminescence intensity was obtained when samples were prepared ...

Single molecule fluorescence resonance energy transfer scanning near-field optical microscopy

Giovanni Dietler, Serguei Sekatski

The first single molecule fluorescence resonant energy transfer scanning near-field optical microscope (FRET SNOM) images of CdSe nanocrystal (donor) deposited onto the glass slide surface are presented. Images were obtained using the earlier proposed FRET ...

Generalized Bombieri-Lagarias' Theorem And Generalized Li'S Criterion With Its Arithmetic Interpretation

Serguei Sekatski

We show that Li's criterion equivalent to the Riemann hypothesis, i.e., the statement that the sums k(n) = Sigma(rho)(1-(1-1/rho)(n)) over zeros of the Riemann xi-function and the derivatives lambda(n) equivalent to 1/(n-1)! d(n)/dz(n)(z(n-1) ln (xi(z)))ve ...

Single molecule fluorescence resonance energy transfer scanning near-field optical microscopy: potentials and challenges

Giovanni Dietler, Mounir Driss Mensi, Serguei Sekatski, Anton Smirnov, Kanat Dukenbayev, Andrey Mikhaylov, Ekaterina Rostova

A few years ago, single molecule Fluorescence Resonance Energy Transfer Scanning Near-Field Optical Microscope (FRET SNOM) images were demonstrated using CdSe semiconductor nanocrystal-dye molecules as donor-acceptor pairs. Corresponding experiments reveal ...

Near-field scanning optical microscopy using polymethylmethacrylate optical fiber probes

Giovanni Dietler, Mounir Driss Mensi, Serguei Sekatski, Kanat Dukenbayev

We report the first use of polymethylmethacrylate (PMMA) optical fiber-made probes for scanning near-field optical microscopy (SNOM). The sharp tips were prepared by chemical etching of the fibers in ethyl acetate, and the probes were prepared by proper gl ...

On equalities involving integrals of the logarithm of the Riemann zeta-function and equivalent to the Riemann hypothesis

Serguei Sekatski

By using the generalized Littlewood theorem about a contour integral involving the logarithm of an analytic function, we show how an infinite number of integral equalities involving integrals of the logarithm of the Riemann zeta-function and equivalent to ...

High-Q surface modes in photonic crystal/iron garnet film heterostructures for sensor applications

Giovanni Dietler, Serguei Sekatski

A novel type of a plasmonic sensor based on a magnetophotonic plasmonic heterostructure with an ultrahigh-Q resonance is considered. A magnetoplasmonic resonance with an angular width of 0.06A degrees, which corresponds to a Q factor of 700 and is a record ...

Enhancement of hypersensitive transitions of rare-earth ions in the near field of nanoobjects

Serguei Sekatski

The change of intensities of optical transitions of atoms, molecules, and their ions in the near field of nanoobjects is of interest for researchers from both basic and applied points of view. The concept of a near field was used as early as the 1960s to s ...

Ultrasharp carbon whisker optical fiber probes for scanning near-field optical microscopy

Giovanni Dietler, Mounir Driss Mensi, Serguei Sekatski, Andrey Mikhaylov

We report the growth of ultrasharp carbon whiskers onto apertured near-field optical glass fiber probes. The ultrasharp carbon whiskers are produced by the electron-assisted dissociation of residual oil vapors present in the vacuum chamber during the elect ...
