Progress and Application of Spatial Modulation Spectroscopy Technique for Detection of Extinction Cross Section of Single Nanoparticle
It is crucial to characterize optical properties of nanomaterials for application and development of nanotechnology. Specifically, instead of averaging the observation across a large number of particles, measuring the spectra of a single nanoparticle has recently gained considerable attention, which can accurately and quantitatively analyze itself and its surrounding environment. Among various near-field and far-field approaches, the spatial modulation spectroscopy (SMS) technique can be employed to determine the extinction cross-section spectra using a high signal-to-noise ratio. In this paper, we introduce the modulation scheme, approach development, applications, and the latest research progress of SMS technique, and discuss its prospect for the future application.
