摘要： An ultraviolet light generation target includes a light emitting layer. The light emitting layer contains a YPO4 crystal to which at least scandium (Sc) is added, and receives an electron beam to generate ultraviolet light. Further, a method of manufacturing the ultraviolet light generation target includes a first step of preparing a mixture containing yttrium (Y) oxide, Sc oxide, phosphoric acid, and a liquid, a second step of evaporating the liquid, and a third step of firing the mixture.

摘要： Provided is a light-emitting device and a method for manufacturing the same which avoid a distinct color unevenness during the light emission even if variations are present among the light-emitting elements in the concentration of the phosphor that precipitates in the resin for sealing the light-emitting elements. The light-emitting device includes a substrate, a plurality of light-emitting elements that are mounted on the substrate, a first resin layer that integrally seals the light-emitting elements and includes a first phosphor that is excited by light from the light-emitting elements at a concentration that is high as it goes to a lower end near the substrate from an upper end distant from the substrate, and a second resin layer that is provided at an upper side of the first resin layer and includes a second phosphor that is excited by light from the light-emitting elements at a uniform concentration.
