Single-walled carbon nanotube,Near-infrared perfect absorber

Maximizing near-infrared light absorption in thin films is of great importance for improving the performance of various optical and thermal radiation control devices such as sensors and wave-selective emitters. Here, we propose a near-infrared perfect absorber based on a simple stacked structure without using metals that exploits the strong exciton resonance of semiconducting single-walled carbon nanotubes (SWCNTs). We report the design and fabrication of a four-layer structure consisting of a structure-sorted SWCNT thin films and transparent dielectric material (magnesium fluoride) thin films, achieving an absorptance of 0.96 at a wavelength of 1046 nm.
