Energy transfer and charge transfer between semiconducting nanocrystals and transition metal dichalcogenide monolayers

Abstract

Nowadays, as a result of the emergence of low-dimensional hybrid structures, the scientific community is interested in their interfacial carrier dynamics, including charge transfer and energy transfer. By combining the...

Molybdenum disulfide nanostructures coupled with metal plasmonics for improved electronic and photonic performances

“…Due to the similar semiconducting and metallic properties of MoS 2 with other TMDs materials, a series of TMDs nanostructures, such as WS 2 , MoSe 2 , WSe 2 , have been reported to be combined with plasmonic materials. They exhibited consistent routes in terms of the composite preparation, photo-/electron-characteristics, 106 and intriguing applications. The development of coupled nanostructures based on emerging plasmonics and MoS 2 possesses high value in directing the fundamental research and practical applications.…”

Electron transfer and energy exchange between a covalent organic framework and CuFeS2 nanoparticles

“…Furthermore, an additional mechanism is proposed if the excitation wavelength is close to the SPR at the visible range. When there is an overlap of the CuFeS 2 absorption with the COFs’ emission, at the SPR wavelength, the energy exchange is likely to happen through plasmon–exciton interactions, 63 including forward (PIRET) and backward (FRET) directions of energy flow, quenching the system and therefore inducing a faster lifetime 64–67 (Scheme 1ii). The quenching of fluorescence can be attributed to the LSPR-mediated local heating of the surrounding environment, but it's excluded from this study, as also the potential influence of the temperature.…”

Charge Transfer from Quantum-Confined 0D, 1D, and 2D Nanocrystals

“…Early reviews focus on photochemistry and redox reactions on the surface of non-quantum-confined colloidal nanocrystals and nanocrystalline thin films. , Interfacial charge transfer in donor–bridge–acceptor systems on nanoparticles and bulk metals and in solar energy conversion systems, including QD-sensitized solar cells, ,, has also been reviewed. Charge transfer dynamics from quantum-confined NCs to molecular acceptors, − redox enzymes, and 2D transition metal dichalcogenides have been subjects of more recent review articles, including a comprehensive Review published in this journal . Advances in the use of quantum-confined nanocrystals in photocatalytic reactions, including QDs, , NRs, , and NPLs, have also been reviewed.…”
