摘要:
Copper-carbon core-shell nanoparticles were synthesized on a large scale by metal-organic chemical vapor deposition using copper (II) acetylacetonate as precursor. It was shown that the thickness of carbon shell and the diameter of copper cores could be easily tuned from 1.5 to 7.9 nm and from 15 to 21 nm, respectively, by controlling the reaction temperature and the flow of carrier gas in the synthesis process. The ultraviolet-visible absorption and fluorescence spectral analyses demonstrated that the thickness and crystallinity of the carbon shells had a significant effect on the surface-pla...
