Polarization-resolved extinction and scattering cross-section of individual gold nanoparticles measured by wide-field microscopy on a large ensemble

Lukas M Payne, Wolfgang Langbein, Paola Borri

We report a simple, rapid, and quantitative wide-field technique to measure the optical extinction ${\sigma }_{\mathrm{ext}}$ and scattering ${\sigma }_{\mathrm{sca}}$ cross-section of single nanoparticles…
