Time resolved study of photoluminescence from gold nanostructures


EMSL Project ID
3070

Abstract

Under intense pulsed laser illumination, gold photoluminesces, showing a wavelength dependence in the visible which depends on the morphology and shape of the gold surface or nanostructure. On the time scale of picoseconds there should be a competition between electron-electron scattering, which is a bulk property, and electron-surface scattering, which depends on the shape, which will determine the optical response of the nanostructure. We wish to make a comparative study of the time dependence of bulk and nanostructured samples to determine the role of the surface on the ultrafast electron dynamics.
