Morphology, structure, and growth of nanoparticles produced in a carbon arc.

摘要: The morphology and crystalline microstructure of carbon-encapsulated nanoparticles produced in a Huffman-Kr\"atschmer fullerene reactor are studied systematically as function location within the reactor. X-ray powder diffraction high-resolution transmission electron microscopy used to characterize harvested from walls inner outer cores cathode deposit. We observe increased graphitization crystallinity, more faceting, gaps between nanoparticle encapsulating carbon cages deposit when compared wall powder. propose growth model based on gas-phase nucleation explain these observations, linking arc synthesis existing work gas aggregation cluster sources.
