The room temperature stability of nanometer-sized silver clusters in silica matrices has been investigated by following the temporal evolution of their surface plasmon absorption. Ag clusters in SiO2 were prepared by either annealing silica samples doped w ...
The excitation of a surface plasmon polariton (SPP) wave on a metal-air interface by a diffraction grating under monochromatic normal illumination is investigated numerically. The influence of the different experimental parameters (grating thickness, perio ...
The paper reports on the deposition of thin antimony (Sb)-doped SnO2 films onto gold and silver substrates using magnetron sputtering. The influence of the SnO2:Sb film on the electrochemical and surface plasmon resonance properties is investigated. The be ...
Here, we report on an aqueous room temperature synthesis method for the production of gold nanoparticles that have a number (> 4) of branches ultimately resembling the shape of sea urchins. The particles are synthesized in the presence of water soluble thi ...
The polarization sensitivity of optical resonant dipole antennas is investigated numerically using the Green's tensor technique. The electric field-intensity in the feed-gap of the antenna is calculated as function of the polarization of the incident field ...
We study the forces generated by an electromagnetic field on two coupled gold nanowires at the vicinity of the plasmon resonance wavelength. Two different regimes are observed, depending on the separation distance d between the wires. In the near field cou ...
n this paper we investigate for the first time the near-field optical behavior of two-dimensional Fibonacci plasmonic lattices fabricated by electron-beam lithography on transparent quartz substrates. In particular, by performing near-field optical microsc ...
We use rigorous diffraction theory to analyze the force on elliptical cylinders made from silver as a function of the elongation. We find that, when the wires are illuminated at the plasmon wavelength and placed in a highly focused Gaussian beam, they are ...
We study in detail the. optical forces generated by a plasmonic trap on a plasmonic nanoparticle. The permittivity of the trapped particle is tuned using a Drude model. The interplay between the plasmon resonances of the trap and of the particle can produc ...
The authors measured the ultrafast response of triangular silver nanoparticles upon femtosecond excitation of their plasmon resonance. After a fast electron relaxation, the signature of a bimodal mech. vibration of the particle is apparent as a spectral mo ...
