Abstract

Development of novel nanoscale devices requires unique functional nanomaterials. Furthermore, chemical design of different nanoparticles in one unit is a complex task, particularly the application of self-assembly J-aggregates, which can substantially advance the nanomaterial’s properties due to resonant delocalization of excitons. Here, we have demonstrated for the first time formation of resonantly coherent J-aggregates on carbon nanotubes with highly efficient energy transfer from the aggregates to the nanotubes. All the energy of photons absorbed by the aggregates is conveyed to the nanotubes, completely quenching the J-band emission and photosensitizing the nanotubes. Overall, we discovered formation of two types of J-aggregates, where one type is related to self-assembly of cis -isomers on the nanotube surface and the second type is associated to self-organizing trans -isomers into free J-aggregates without the nanotubes. Importantly, the J-aggregates on carbon nanotubes with strong energy transfer peaks of photoluminescence in the near infrared range are of high interest for practical applications on biomedical imaging and nanoscale optoelectronic and nanophotonic devices.

  • High durability of hybrid organic-inorganic nanocomposite systems has been demonstrated in J-aggregate-based photosensibilization and photoluminescence amplification in SWNTs and NIR emitting PbS quantum dots.

    “The high durability of such systems has been demonstrated in J-aggregate-based photosensibilization and photoluminescence amplification in SWNTs and NIR emitting PbS quantum dots,228,229 organic dye-coated RENPs providing a tunable excitation, and increased SWIR luminescence with up to 40-fold enhancement.230,231”

    From The Pursuit of Shortwave Infrared-Emitting Nanoparticles with Bright Fluorescence through Molecular Design and Excited-State Engineering of Molecular Aggregates (2022) · cites this paper as [229]

    The Results and Discussion (page unavailable) report J-aggregate sensitization of SWNT emission and roughly 3.8–4.5-fold photoluminescence enhancement. The cited paper does not demonstrate high durability or address NIR-emitting PbS quantum dots; the latter may be covered by the other citation attached to the sentence. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
