Abstract

We report the fabrication of hybridized nanocrystals by using C 60 nanocrystals as a organic core and gold nanoparticles as a metallic shell. The C60 nanoparticles were prepared by reprecipitation method. The morphology of C60 nanocrystals can control the various shapes by selecting the proper combination of good and poor solvents in the reprecipitation method. Moreover, by changing the concentration of C60 solution can control their morphology and sizes. After preparing C60 nanocrystals dispersion, HAuCl4 water solution was added into the C60 nanocrystals dispersion and UV-irradiated for reduce from Au+ to Au. Hybridized nanocrystals could be formed when pyridine was used as a good solvent and methanol was used as a poor solvent. We also succeeded in preparation of C60 nanocrystals coated by Ag nanoparticles. Details of the preparation processes and their optical properties will be reported.
