Abstract

A study was conducted to propose the utilization of single-walled carbon nanotubes (SWCNT) as a photon antenna that serves as an effective molecular heater around the near-infrared (NIR) region. The study demonstrates that SWCNTs are nanomaterials that possess significant electrical, mechanical,and thermal properties. It was also shown that characteristic absorption bands in the NIR region are formed, due to the interband transition between the mirror-image spikes in the density of states of the SWCNTs. It was also demonstrated that these SWCNTs can be used as molecular heaters through photothermal conversion phenomena that occur due to a nonradiative process of excited SWCNT by NIR irradiation. The results indicate that the SWCNTs in the composite gel remain structurally intact, without formation of outflow of SWCNTs from the gel.
