Advanced Photonic Hybrid Materials

Abstract

This work had three results: 1) construction of gold "bipyramid" nanostructures for tuning the plasmon resonance between visible/IR wavelengths; these structures with a high aspect ratio allowed extension of the local surface plasmon resonance (LSPR) toward IR wavelengths as far as 1850nm. 2) Optical transmission properties of dispersions of self-orienting gold nanoparticles (spherical and bipyramidal) in sol-gel hybrid silica, which could be used as optical limiters (transmitting at low levels but blocking high intensities); this has been done in liquid, but this study attempted a stable solid-state glass. The transmission spectra showed well-defined plasmon absorption peaks without redshift, indicating little or no LSPR coupling.
