We discuss the design of an optical system that allows measurement of 600-1650 nm emission spectra for individual nanoparticles (NPs), laser-heated in an electrodynamic trap in controlled atmospheres. An approach to calibration of absolute intensity versus wavelength for very low emission intensities is discussed, and examples of NP graphite and carbon black spectra are used to illustrate the methodology.
我们讨论了一种光学系统的设计，该系统能够测量在可控气氛中的电动阱中被激光加热的单个纳米颗粒（NP）的600 - 1650纳米发射光谱。讨论了一种针对极低发射强度的绝对强度与波长校准方法，并使用NP石墨和炭黑光谱的示例来说明该方法。
