Nanotechnologies - Characterization of single-wall carbon nanotubes using near infrared photoluminescence spectroscopy

This document gives guidelines for the characterization of single-wall carbon nanotubes (SWCNTs) using near-infrared (NIR) photoluminescence (PL) spectroscopy. It provides a measurement method for the determination of the chiral indices of the semi-conducting SWCNTs in a sample and their relative integrated PL intensities. The method can be expanded to estimate the relative mass concentrations of semi-conducting SWCNTs in a sample from their measured integrated PL intensities and knowledge of their PL cross-sections.
