Optical properties of oxidized single-wall carbon nanotubes

Carbon Nanotube Photoluminescence Modulation by Local Chemical and Supramolecular Chemical Functionalization

“… ,,,,,− Hereafter, the energy values of the intrinsic exciton PL peak and the red-shifted PL peak are referred to as E 11 and E 11 *, respectively. The red-shifted PL feature of the doped nanotubes has been attributed to a reduced band gap and exciton energy of the dopant-induced local states. ,,,− Microscopically, these defects were attributed to ether- or epoxide-type oxygen adducts ,,, that induce local midgap states with specific energies depending on the details of the local chemical structures (Figure ). This was further confirmed by comparing the experimental results of the individual SWCNTs by density functional theory (DFT) calculations .…”

Roles of sulfur in floating-catalyst CVD growth of single-walled carbon nanotubes for transparent conductive film applications

“…2.3c) [19][20][21]. [20] showing , and transitions. Each blue dot corresponds to one transition state of a specific diameter semiconducting-SWCNT and red dot of metallic-SWCNT.…”

“…The energy of these optical transitions in a SWCNT is inversely proportional to the nanotube diameter and the mean diameter of SWCNTs bulk sample can be estimated by combining the energy of these transitions with the Kataura plot ( Fig. 2.3c) [19][20][21]. [20] showing , and transitions.…”

Simulations of Benzene and Hydrogen-Sulfide Gas Detector Based on Single-Walled Carbon Nanotube over Intrinsic 4H-SiC Substrate

“…CNT has been accepted as an active photo-responsive material. It has several optical attributes like ultraviolet absorption, polarization selectivity, and infrared absorption [48][49][50][51]. It is possible to use this mechanism of change in photocurrent as an additional mechanism along with the conventional techniques to improve the device selectivity and accuracy.…”
