Abstract:
A light-emitting device includes a light-emitting element which emits ultraviolet light, and a fluorescent layer provided on the light-emitting element. The fluorescent layer includes fluorescent particles. The fluorescent particles are excited by the ultraviolet light emitted by the light-emitting element and the excited fluorescent particles emit ultraviolet light of a wavelength longer than the ultraviolet light emitted by the light-emitting element.
