Plasmon delocalization onset in finite sized nanostructures

Olivier Martin, Arash Farhang

The transition from localized to delocalized plasmons (i.e. the transition from a situation where the decay length of a travelling surface plasma wave is greater than its propagation distance to a situation where it is smaller) and hence the onset of plasm ...

YAG:Ce nanoparticle based converter layer for white LEDs

Elison de Nazareth Matioli

Our work is devoted to the development of YAG:Ce3+ nanoparticle based films for white LEDs. Very stable suspensions of YAG:Ce nanoparticles are synthesized by a glycothermal method at relatively low temperature (300 degrees C). Protected annealing in a sil ...

Optical limiting with complex plasmonic nanoparticles

Francesco Stellacci

Optical limiting by suspensions of Au nanoparticles is enhanced by several orders of magnitude with the use of complex plasmonic shapes, such as spined 'nanourchins,' instead of nanospheres. Similar enhancements are observed by changing the material of nan ...

Surface plasmon resonance of gold nanoparticles assemblies at liquid | liquid interfaces

Hubert Girault, Mohamad Hojeij, Nathalie Younan, Lydie Ribeaucourt

Surface plasmon resonance (SPR) was observed when a planar close-packed assembly of gold nanoparticles (Au NPs) is adsorbed at the water|1,2-dichloroethane interface. Aqueous gold nanoparticles, 13 or 16 nm in diameter, are deposited at the interface by ad ...

Optical trapping and sensing with plasmonic dipole antennas

Olivier Martin

In this work, we study how to use a plasmonic dipole antenna as a multifunctional nanodevice for surface-enhanced Raman spectroscopy (SERS), localized surface plasmon resonance (LSPR) -based sensing and optical trapping. An analytical model is implemented ...

Photoelectrochemical properties of sensitized thin films

Mohamad Hojeij

In recent years, the fabrication of novel ultrathin film systems featuring multi-functionalities has been extensively studied due to their potential applications in photonics, sensors and solar cells. In a general sense, the primary goal of the present the ...

Quasi-periodic distribution of plasmon modes in two-dimensional Fibonacci arrays of metal nanoparticles

Francesco Stellacci

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 ...

Linear and nonlinear optical properties of aggregated spherical gold nanoparticles

Akihiro Sato

We have fabricated gold nanospheres composite multilayer films using the layer-by-layer (LbL) self-assembly technique, and have investigated the aggregate states of the gold nanosphere. The gold nanospheres composite multilayer films were fabricated by con ...

Instability of Ag nanoparticles in SiO2 at ambient conditions

Giulia Di Domenicantonio, Olivier Eugster

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 ...

High-Yield Synthesis of Multi-Branched Urchin-Like Gold Nanoparticles

Francesco Stellacci

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 ...
