Semiconductor single-walled carbon nanotubes emitting near-infrared light

摘要

Exemplary Embodiments of the invention address the problem of providing semiconductor single-layer carbon nanotubes in which the light emission energy thereof is lowered by approximately 300 meV, and a method for manufacturing the same. In one embodiments of the invention, by applying a method for directly irradiating semiconductor single-layer carbon nanotubes with ultraviolet light in atmospheric air, ozone is generated in the atmosphere, a gram amount of oxygen atoms is introduced to the semiconductor single-layer carbon nanotubes, and semiconductor single-layer carbon nanotubes in which the light emission energy thereof is lowered by approximately 300 meV.
