Photocatalyst reaction is a reaction occurring only on the surface of a particle. Therefore ultraviolet radiation needs to be uniformly applied to the surface of a particle. However, a special device is required, and the collection of the photocatalyst particles is costly when replaced. The photocatalyst reaction is difficult to apply to large reaction vessels, particularly to external light source type. These problems have been solved. An EL fiber having a function of emitting ultraviolet light of a wavelength shorter than 400 nm or visible light is characterized in that the cross-section structure of the EL fiber comprises an inner electrode disposed at the radial center, an inside insulating layer formed around the inner electrode, a light-emitting layer, an outer electrode, and a protective layer formed on the outermost surface, and light is emitted when an alternating electric field is applied between the electrodes. |
