Title (EN) CORE-SHELL HETEROSTRUCTURES COMPOSED OF METAL NANOPARTICLE CORE AND TRANSITION METAL DICHALCOGENIDE SHELL
(FR) HÉTÉROSTRUCTURES NOYAU-ENVELOPPE COMPOSÉES D'UN NOYAU DE NANOPARTICULE MÉTALLIQUE ET D'UNE ENVELOPPE DE DICHALCOGÉNURE DE MÉTAL DE TRANSITION
Abstract:
(EN) Provided herein are core-shell heterostructures design comprising a metal (e.g., noble metal) nanoparticle core and a transition metal dichalcogenide (TMD) shell, and methods of preparation and use thereof. In particular embodiments, the core-shell heterostructures described herein are synthesized by direct growth of a monolayer or multilayer fullerene-like TMD shell on a metal (e.g., noble metal) nanoparticle core, exhibit unique Raman scattering and photoluminescence characteristics, and are useful, for example, in plasmonic hot electron enhanced optics and optoelectronics.
(FR) La présente invention concerne une conception d'hétérostructures noyau-enveloppe comprenant un noyau de nanoparticule métallique (par exemple, un métal noble) et une enveloppe de dichalcogénure de métal de transition (TMD), et des procédés de préparation et d'utilisation de cette dernière. Dans des modes de réalisation particuliers, les hétérostructures cœur-enveloppe décrites ici sont synthétisées par croissance directe d'une enveloppe TMD de type fullerène monocouche ou multicouche sur un noyau de nanoparticules métallique (par exemple, un métal noble), présentent des caractéristiques uniques de diffusion Raman et de photoluminescence, et sont utiles, par exemple, dans une optique et l'optoélectronique améliorées à électrons chauds plasmoniques.
