“…Kappes et al developed an approach to combine and compare the PL (spectroscopic) and AFM (topographical) information for the same individual nanotubes on a substrate. 585 The structure of luminescent s-SWCNTs was probed by PL spectroscopy and the diameter and length as well as spatial position of deposited SWCNTs were accurately determined by high-resolution AFM imaging (Figure 74a−c). This approach can be employed to determine the (n,m) abundance by probing the individual nanotubes one by one.…”

Single-walled carbon nanotubes (SWCNTs) have been attracting tremendous attention owing to their structure (chirality) dependent outstanding properties, which endow them with great potential in a wide range of applications. The preparation of chirality-pure SWCNTs is not only a great scientific challenge but also a crucial requirement for many high-end applications. As such, research activities in this area over the last two decades have been very extensive. In this review, we summarize recent achievements and accumulated knowledge thus far and discuss future developments and remaining challenges from three aspects: controlled growth, postsynthesis sorting, and characterization techniques. In the growth part, we focus on the mechanism of chirality-controlled growth and catalyst design. In the sorting part, we organize and analyze existing literature based on sorting targets rather than methods. Since chirality assignment and quantification is essential in the study of selective preparation, we also include in the last part a comprehensive description and discussion of characterization techniques for SWCNTs. It is our view that even though progress made in this area is impressive, more efforts are still needed to develop both methodologies for preparing ultrapure (e.g., >99.99%) SWCNTs in large quantity and nondestructive fast characterization techniques with high spatial resolution for various nanotube samples.

“…Another signature of aggregated SWNTs appears to be their broadened and red-shifted PL emission. 19,20 For instance, the Raman and PL spectra of the localized emitters indicated by arrows in Figs. 3(a) and 3(c) can be assigned to such aggregates (as also supported by complementary PL and Raman spectra of other sample regions -not shown). As in the previous example, combined Raman and PL imaging facilitates the (n,m)-assignment of detected nanotubes.…”

We describe a microscope which allows simultaneous acquisition of Raman and near-infrared photoluminescence (NIR-PL) spectra and images. The instrument comprises an appropriately modified commercial Raman microscope, utilizes 785 nm excitation laser, and includes two detection channels for Raman and PL within the spectral ranges of ∼787-1000 nm (∼40-2700 cm(-1) Raman shift) and ∼1050-1600 nm, respectively. The configuration can however be easily adapted for other excitation wavelengths and detection ranges. The possibility to simultaneously measure both Raman and NIR-PL spectra - exactly at the same sample locations - can be useful for various applications, for instance, for the characterisation of single-walled carbon nanotubes.

“…[406,413] In fact, to improve the characterization accuracy, some new characterization techniques based on the combination of spectroscopy and microscopy, have been developed. [402,[413][414][415][416][417] For example, Kappes et al combined AFM with the PL microscopy to investigate the topographical and spectroscopic information of individual SWCNTs on sapphire. [414] Similar technique was used for the chirality assignment and purity evaluation of SWCNTs by Weisman et al, [415] but one by one measurement is required.…”

Structural control of single-wall carbon nanotubes (SWCNTs) with uniform properties is critical not only for their property modulation and functional design but also for applications in electronics, optics, and optoelectronics. To achieve this goal, various separation techniques have been developed in the past 20 years through which separation of high-purity semiconducting/metallic SWCNTs, single-chirality species, and even their enantiomers have been achieved. This progress has promoted the property modulation of SWCNTs and the development of SWCNT-based optoelectronic devices. Here, the recent advances in the structure separation of SWCNTs are reviewed, from metallic/semiconducting SWCNTs, to single-chirality species, and to enantiomers by several typical separation techniques and the application of the corresponding sorted SWCNTs. Based on the separation procedure, efficiency, and scalability, as well as, the separable SWCNT species, purity, and quantity, the advantages and disadvantages of various separation techniques are compared. Combined with the requirements of SWCNT application, the challenges, prospects, and development direction of structure separation are further discussed.
