摘要
纳米材料的表征是纳米技术应用和发展的基础,特别是测量单个纳米颗粒的光谱近年来引起了广泛关注,它可以排除平均效应从而对其本身及周围环境进行精确的定量分析。为此多种近场或远场探测纳米颗粒的方法被提出,其中空间调制测量(SMS)技术可以对消光截面谱的绝对大小进行高信噪比的测量。本文着重介绍SMS技术的调制方式、发展历程、应用以及最新研究进展,并对该技术在未来的应用前景进行展望。
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.
