Abstract

The optical extinction spectra of single gold nanoparticles stabilized by surfactant molecules are investigated using the spatial modulation spectroscopy technique. The experimental results are compared to computed spectra, focussing on the width of the surface plasmon resonance. It is shown to strongly vary from particle to particle, independently of their size and dielectric environment. This demonstrates the key role of the interface conditions on the width of the surface plasmon resonance for surfactant-stabilized metal nanoparticles.
