Self-assembled high aspect ratio gold nanostar/graphene oxide hybrid nanorolls

摘要: Owing to their unique properties and potential applications in nanoelectronics, graphene its derivatives have received extensive attention over the last decade. Noble metal nanostructures, on other hand, enable confinement manipulation of light at nanoscale. Integration nanocarbons plasmonic nanostructures is expected result synergistic optoelectronic that can potentially revolutionize design fabrication devices. In this letter, we demonstrate a simple self-assembly approach achieve ensemble gold nanostars oxide. Gold are directly nucleated grown surface oxide by situ reduction method producing differential charged hybrid macroanionic sheets, which then kinetically rolled simultaneously assembled into high aspect ratio nanorolls means interplay kinetics graphene–gold interactions.
