Thermal emission spectroscopy for single nanoparticle temperature measurement: optical system design and calibration
- Univ. of Utah, Salt Lake City, UT (United States)
Here, we report on 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. A method 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.
