Nanotubes Show Their True Colours

Why do some thin films of single-wall carbon nanotubes take on colourful hues even though as-synthesized films are usually black? A team of researchers in Finland, the US and China has now come up with a possible answer in a development that could prove useful for future display screens and solar cells.
