We present simple phenomenological evidence linking the optical and tensile properties of nanocomposites of metallic particles in polymer melts to their method of preparation. We made films containing silver nanoprisms embedded in a matrix of poly (vinylpyrrolidone), PVP, or poly (ethylene oxide), PEO, by solvent casting or spin coating. Microscopy imaging revealed that the silver nanoparticles can...
A monodisperse alcosol containing 0.1 wt. % 15 nm gold particles was subjected to controlled flow through a metal capillary exposed to an electric field at the ambient temperature to generate an electrohydrodynamic jet, which subsequently disintegrated into droplets. A silicon substrate was used to collect the droplets and prepare gold films. By varying the deposition time, we have prepared gold films...
We report on the first realization of a hyperspectral imaging (HSI) technique of surface plasmon polaritons excited in metallic nanostructures by a scanning electron beam. The HSI image is formed by scanning a plasmonic structure with a focused electron beam, simultaneously recording the spectra of light emission from decoupled plasmons by a spectrum analyzer. By scanning the sample in this manner,...
