Article
Full-text available
The electromagnetic momentum loss approach is applied to predict the plasmon drag effect in profile-modulated gold films at different amplitudes of surface modulations. Direct proportionality of energy and momentum transfer in interactions of plasmons and free electrons in metal is proven to be valid for surfaces with relatively low height modulati...
Article
Plasmon drag effect is studied theoretically and experimentally in gold films with a sine-wave height profile. Numerical simulations based on the modified electromagnetic momentum loss approach are shown to correctly describe the photoinduced voltage associated with propagating surface plasmon polaritons. Direct proportionality of energy and moment...

Single crystals of Ln(NO 3 ) 3 ·Bpy 2 where Ln = Eu, Gd, Nd, Tm, Er, La and Yb were fabricated and characterized. Materials have good optical quality, can be excited at UV or the rare earth ion transitions, demonstrate efficient luminescence and are suitable for thin film fabrication. Fabrication approaches and possible applications are discussed.
Conference Paper
Plasmonics is promising for future electronics as it can combine optical speed of operation with nanoscale size, something which is not possible with traditional optics and electronics [1]. Coupling of photons, plasmonic excitations and electrons is of key importance as it provides opportunities to monitor or control plasmonic nanocircuits electric...
Article
Full-text available
We have synthesized gyroidal TiN metamaterials, studied their optical properties, and compared them with the optical properties of the TiN thin films fabricated using reactive magnetron sputtering. The plasma frequency, ωp, and the corresponding free carrier concentration, N, in the gyroid samples were found to be much lower than those in thin film...
Article
Full-text available
We demonstrate the enhancement of magnetic dipole spontaneous emission from Eu3+ ions by an engineered plasmonic nanostructure that controls the electromagnetic environment of the emitter. Using an optical microscope setup, an enhancement in the intensity of the Eu3+ magnetic dipole emission was observed for emitters located in close vicinity to a...
Article
Full-text available
Inter- and multidisciplinary training has been advocated for graduate students as the problems facing science and engineering become increasingly complex. The Integrative Graduate Education Research and Traineeship on Magnetic and Nanostructured Materials (IGERT-MNM) is a collaboration between Purdue University, Cornell University, and Norfolk Stat...
Poster
Full-text available
Plasmonic systems and metamaterials attract much attention due to novel optical effects predicted and observed in these systems and many promising applications in industry and biomedical field. One of the effects is strong modification of optical environment in close vicinity of plasmonic structures, which can significantly affect excitation and em...
Conference Paper
Full-text available
We probe effects of field enhancements in silver-dielectric layers using a highly luminescent organic system with Eu3+. Significant enhancement in the excitation spectra is observed at the spectral range corresponding to epsilon-near zero for silver.
Conference Paper
Full-text available
We use spontaneous emission of Eu3+ ions as a spectroscopic tool to probe modifications of optical fields in close vicinity of metal and under the conditions of the optically-induced magnetic resonance.
Article
Full-text available
Strong modification of spontaneous emission of Eu3+ ions placed in close vicinity to thin and thick gold and silver films was clearly demonstrated in a microscope setup separately for electric and magnetic dipole transitions. We have shown that the magnetic transition was very sensitive to the thickness of the gold substrate and behaved distinctly...
Article
Full-text available
In order to investigate the effects of plasmonic environments on spontaneous emission of magnetic and electric dipoles, we have studied luminescence of Eu<sup>3+</sup> ions in close vicinity to gold nanostrip arrays. Significant changes in the emission kinetics, emission polarization, and radiation patterns have been observed in the wavelength rang...
Conference Paper
Strongly different behavior of magnetic and electric dipole spontaneous emission is observed in close vicinity of gold and silver. Effects can be used to study and map modifications of local optical environment in plasmonic systems
Article
Luminescence of Eu ions was used to study effects of plasmonic environment on spontaneous emission of magnetic and electric dipoles in several nanostructured systems, including gold nanostrips, gold and silver nanomesh and thin films. Significant changes in polarization and radiation patterns were observed in the spectral range of plasmonic resonan...

Conference Paper
Spontaneous emission of Eu3+ is significantly modified in close vicinity of metal and nanostructured metal systems. The effects are different than those predicted by the “image model”, and ascribed to strong coupling with plasmonic modes. ... Unique properties of plasmonic nanostructured systems are associated with dramatic modifications of pho...

Article
Acceleration of the longitudinal spin relaxation kinetics, associated with the presence of magnetic nanoparticles (MNPs), has been analysed based on the diffusion mechanism of the spin relaxation. The predictions of the outer sphere model were tested in viscous systems and complex multiphase systems, where different components had different mobilit...
