“…The high sensitivity of PL in SWCNT systems is very useful in sensing applications [23]. In order to fully exploit the PL features of SWCNTs in biomarkers [24] and optoelectronic devices [25], strong and environmentally stable PL signatures are required. However, SWCNTs exhibit all of their constituent carbon atoms on their sidewalls, and are extremely sensitive to their environments.…”

Double walled carbon nanotubes (DWCNTs) are considered an ideal model for studying the coupling interactions between different concentric shells in multi-walled CNTs. Due to their intrinsic coaxial structures they are mechanically, thermally, and structurally more stable than single walled CNTs. Geometrically, owing to the buffer-like function of the outer tubes in DWCNTs, the inner tubes exhibit exciting transport and optical properties that lend them promise in the fabrication of field-effect transistors, stable field emitters, and lithium ion batteries. In addition, by utilizing the outer tube chemistry, DWCNTs can be useful for anchoring semiconducting quantum dots and also as effective multifunctional fillers in producing tough, conductive transparent polymer films. The inner tubes meanwhile preserve their excitonic transitions. This article reviews the synthesis of DWCNTs, their electronic structure, transport, and mechanical properties, and their potential uses.

“…4 In that work, the nanotube samples had dimensions of 3.5ϫ 0.5 mm 2 with a thickness in the range of 40 nm-1 m. No bolometric response could be detected for nonsuspended nanotube films. In this letter, we report the results of a proof-of-principle experiment, where we show a strong bolometric response of deposited nanotube bundles to microwave radiation.…”

A cryogenic bolometer has been fabricated using a bundle of single-walled carbon nanotubes as absorber. A bolometric response was observed when the device was exposed to radiation at 110GHz. The temperature response was 0.4mV∕K, with an intrinsic electrical responsivity at low frequency up to 109V∕W and noise equivalent power of 3×10−16W∕Hz1∕2 at 4.2K. The response is largest at input power levels of a few femtowatts and decreases inversely proportional to the input power. Low frequency noise shows a 1∕f dependence.

“…When the incident light polarizes in parallel to the nanotube axis, transitions occur between the sub-bands with i 5 j, and crosspolarized light addresses the transitions between sub-bands with i{j j j~1. After the optical transition, the energy of the exciton is efficiently transferred to the crystal lattice through strong electronphonon interactions, which increases the temperature of the SWCNT 15 . It is noteworthy that although the listed E ii value in Table 1 is applied at room temperature, E ii only increases by approximately 0.05 eV from room temperature to 2100 6 C 38 , which has little effect on the resonant condition.…”

“…Recent light absorption investigations of individual nanotubes have focused on different resonant and nonresonant modes using spatial modulation spectroscopy 12 , polarization-based homodyne microscope 13 , and photoconductivity spectra 14 . However, to avoid the optical detection difficulty from the small cross section of SWCNTs, the light-induced thermal effect was considered a suitable method to study the thermal and optical properties of CNTs, which is also significant to both the function of optical devices 15 and SWCNT species control [16][17][18] . In arrays of nanotubes with mixed structures and chirality, unusual laser-induced ''heat trap'' phenomena have recently been observed 19,20 .…”

The predicted extraordinary properties of carbon nanotubes (CNTs) from theoretical calculations have great potential for many applications. However, reliable experimental determination of intrinsic properties at the single-tube level is currently a matter of concern, and many challenges remain because of the unhandled and nanoscale size of individual nanotubes. Here, we demonstrated a prototype to detect the intrinsic thermal conductivity of the single-wall carbon nanotube (SWCNT) and verify the significant non-resonant optical absorption behavior on tiny nanotubes by integrating the nanotube and ice into a new core-shell design. In particular, a reversible optical visualization method based on the individual suspended ultra-long SWCNT was first developed by wrapping a nanotube with ice in the cryogenic air environment. The light-induced thermal effect on the hybrid core-shell structure was used to melt the ice shell, which subsequently acted as a temperature sensor to verify the intrinsic thermal conductivity of the core-like nanotube. More interestingly, we successfully determined for the first time the thermal response phenomenon of the tiny absorption cross section in SWCNT in the vertical-polarization configuration and the significant non-resonant absorption behavior in the parallel-polarization configuration. These investigations will provide a better understanding for the unique optical behaviors of CNT and enable the detection of intrinsic properties of various one-dimensional nanostructures such as nanotubes, nanowires, and nanoribbons.
