Abstract

Gold-coated C60 nanocrystals were first fabricated successfully. C60 nanocrystals as a core were prepared previously by the reprecipitation method using CS2 as a good solvent and ethanol as a poor solvent. Gold nanoparticles were interestingly deposited on the surface of the C60 nanocrystals core without using any reducing reagent, after adding of HAuCl60 aqueous solution into 10 ml of C60 nanocrystals dispersion. SEM images and powder X-ray diffraction proved the formation of gold nanoparticles. By changing temperature of C60 nanocrystals dispersion liquid after adding HAuCl4 solution, we could control the gold-coating coverage of C60 nanocrystals.
