Carbon in color: First-ever colored thin films of nanotubes created
A method can produce large quantities of pristine single-walled carbon nanotubes in select shades of the rainbow. The secret is a fine-tuned fabrication process -- and a small dose of carbon dioxide. The films could find applications in touch screen technologies or as coating agents for new types of solar cells.
