Atlas shows off 466 carbon nanotube colors

Researchers have created a color atlas for 466 unique varieties of single-walled carbon nanotubes.
The researchers detail the nanotube color atlas in a study about a new method to predict the specific colors of thin films made by combining any of the 466 varieties.
“Carbon, which we see as black, can appear transparent or take on any color of the rainbow,” says Esko Kauppinen, a physicist at Aalto University in Finland and corresponding author of the study in
“The sheet appears black if light is completely absorbed by carbon nanotubes in the sheet. If less than about half of the light is absorbed in the nanotubes, the sheet looks transparent. When the atomic structure of the nanotubes causes only certain colors of light, or wavelengths, to be absorbed, the wavelengths that are not absorbed are reflected as visible colors.” ....
