Abstract: A light-emitting device according to one embodiment includes: a substrate; a graphite thin film disposed on the substrate; and an electrode provided on a second surface of the graphite thin film on an edge portion of the graphite thin film, the second surface of the graphite thin film being opposite from a first surface of the graphite thin film, the first surface of the graphite thin film opposed to the substrate. A plurality of protrusions for supporting the graphite thin film is formed on a surface of the substrate opposed to the graphite thin film, at least over an entire region where the substrate and a portion of the graphite thin film other than the edge portion overlap each other when viewed along a thickness direction of the substrate.

Abstract: A configuration of a time and space-resolved infrared spectroscopic analysis which can be integrated onto a chip is provided. An infrared analysis system includes a light source having a nanocarbon material as a luminescent material, and a photodetector configured to detect an infrared light emitted from the light source and transmitted through or reflected from a sample, wherein the nanocarbon material is provided on a surface of a substrate and configured to output a surface-emitted light.

Abstract: An atom, molecule, atomic layer molecular layer is adhered to a carbon nanotube surface, or the surface is doped with the atom, molecule, atomic layer, or molecular layer, to form a deep localized level so that an exciton is localized. Alternatively, an atom, molecule, inorganic or organic substance of an atomic or molecular layer, a metal, a semiconductor, or an insulator is absorbed to, deposited on, or encapsulated in the carbon tube inside surface to make permittivity of the portion undergoing the absorption, deposition, or encapsulation higher than that of a clean portion free of the absorption, deposition, or encapsulation so that binding energy of the exciton in the clean portion is high, or reduce a band gap of the portion undergoing the absorption, deposition, or encapsulation so that the exciton is confined and localized in the clean portion or the position undergoing the absorption, deposition, or encapsulation.
