Abstract
Nanowires of Au, Ag, Pt, and Pa (1.0-1.4nm diam) have been produced in the capillaries of single-walled carbon nanotubes (SWNTs). The nanowire is sing le;crystalline in some cases. Dispersions of the nanowires in alcohol show longitudinal plasmon absorption bands at different wavelengths, suggesting the presence of a distribution of aspect ratios. A novel phenomenon involvi ng the intercalation of metal layers (similar to 0.5 nm thick) in the inter tubular space of SWNT bundles has been observed. SWNTs decorated by metal n anoparticles are formed in some of the preparations.
