Single-wall carbon nanotubes based near-infrared sensors on flexible substrate

We demonstrate near-infrared sensors based on single wall carbon nanotubes. In order to fabricate near-infrared sensors, single wall carbon nanotubes were dispersed in the aqueous phase. Thin films of single wall carbon nanotubes dispersions have been deposited on flexible polymer substrates. The physical and optical characteristics of both the single wall carbon nanotubes dispersions and the deposited films were studied using a variety of methods. These single wall carbon nanotubes based near-infrared sensors shows excellent sensitivity up to 7.2% at 1.5 mW/mm² laser light illumination and can be used, for instance, for a variety of scientific and industrial applications.
