We perform PL measurements for the CNTs supported by anthracene crystals over the pits (Fig. 1j). Figure 3b shows a typical PLE map of a CNT on anthracene, peaking as sharply as the...

2016年2月12日 · Here, we propose a novel type of ionic sensor complex for detecting CNTs – an organic dye that responds sensitively and selectively to CNTs with a photoluminescent signal. …

2023年12月9日 · PL excitation images are taken by using a three-dimensional motorized stage to scan the CNT/WSe 2 samples in our confocal microscopy system. A PL spectrum is collected …

Carbon nanotubes are unique "one-dimensional" materials, whose hollow fibers (tubes) have a unique and highly ordered atomic and electronic structure, and can be made in a wide range …

2017年3月20日 · Single-walled carbon nanotubes (CNTs) 1, 2, which emit near-infrared (NIR) fluorescence in the long wavelength region (1100–1400 nm: NIR-II) 3, have been expected to...

The PL quantum yield (PLQY) of 2 SWNT species is ∼5 × 10-4, and probably this is lower than the true value due to quenching of the PL in bundles by metallic tubes. Time-resolved PL …

2018年8月1日 · Semiconducting single-walled carbon nanotubes (s-SWCNTs) exhibit unique photoluminescence (PL) and electroluminescence (EL) properties, which suggests the …

Figure 2a shows typical PL spectra from a transferred CNT with a total length of ~50 μm, which are measured at an air-suspended region over a 5-μm-wide trench (red) and at an on-substrate...

The band-gap of semiconducting CNTs has been determined by recent reports of photoluminescence (PL). 4–6 In this paper, we present CNTs that reveal a semiconducting …

2018年1月1日 · The PL measurements are based on bulk characterization of CNTs, and allow differentiation between the semiconducting CNT, based on their band gap energy levels that …
