Abstract: An ultraviolet light emitting device without the use of a p-type semiconductor layer is described. For generating ultraviolet light, an electron beam generator is provided, and an electron beam generated in the electron beam generator is guided to an active layer of an ultraviolet light generator. In the active layer, the electron beam is collided, and electron-hole pairs generated by the collisions are confined in well layers due to barrier layers of the active layer. The confined electrons and holes generate ultraviolet light through recombination.

Abstract: A field electron emission film that is capable of being operated with low electric power and enhancing the uniformity in luminance within the light emission surface contains from 60 to 99.9% by mass of tin-doped indium oxide and from 0.1 to 20% by mass of carbon nanotubes. The film has a structure wherein grooves having a width in a range of from 0.1 to 50 mm are formed in a total extension of 2 mm or more per 1 mm2 on a surface of the film, and carbon nanotubes are exposed on a wall surface of the grooves. After forming an ITO film containing carbon nanotubes on a substrate, grooves are formed on a surface of the ITO film, and the end portions of the carbon nanotubes exposed to the wall surface of the grooves are designated as an emitter.
