Scattering spectroscopy on single plasmonic nanoparticles using a confocal darkfield setup
EPJ Web of Conferences(2023)
摘要
We demonstrate how to measure scattering spectra of single plasmonic nanoparticles using a confocal darkfield setup. We give an overview of considerations and problems we encountered when employing a darkfield technique based on filtering illumination under low angles instead of the conventional high-angle filtering by darkfield objectives.
