Abstract: An ultraviolet light emitting device includes: a first substrate; a second substrate; a gas in a space between the first substrate and the second substrate; electrodes directly or indirectly on a first main surface of the first substrate; a dielectric layer that is located in a first region directly or indirectly on the first main surface of the first substrate and covers the electrodes, the dielectric layer being not located in a second region directly or indirectly on the first main surface of the first substrate, the second region being different from the first region, the first region including regions in which the electrodes are located; and a light-emitting layer that is located in the second region and/or located directly or indirectly on at least one of second and third main surfaces of the second substrate and emits the ultraviolet light in the gas due to electrical discharge between the electrodes.

Abstract: An ultraviolet irradiation apparatus includes: a first substrate; a second substrate; electrodes disposed directly or indirectly on the first substrate; a dielectric layer covering the electrodes; a sealant joining together the first and second substrates; a light-emitting layer that is disposed directly or indirectly on the dielectric layer and/or a surface of the second substrate; and a reaction vessel disposed directly or indirectly on a surface of the second substrate. The reaction vessel includes a tubular structure, an inlet channel and an outlet channel. The tubular structure has a ratio ha/hc of 5 to 10, where ha is a diameter of a circle inscribed in an inner bottom surface of the tubular structure, and hc is an inner height of the tubular structure.

Abstract: An ultraviolet light emitting device comprises: a first substrate having a main surface; a second substrate facing the main surface of the first substrate; a gas in a space between the first substrate and the second substrate; electrodes directly or indirectly on the main surface of the first substrate; a dielectric layer that is located directly or indirectly on the main surface of the first substrate and covers the electrodes; and a first light-emitting layer. The first light-emitting layer is located directly or indirectly on the dielectric layer and emits ultraviolet light in the gas due to electrical discharge between the electrodes. The first light-emitting layer is thicker in first regions on the dielectric layer than in second regions. The second regions include at least part of regions directly above the electrodes.
