Document Type and Number:
WIPO Patent Application WO/2014/065030
Kind Code:
A1
Abstract:
A target for ultraviolet light generation is provided with a substrate that allows ultraviolet light to pass through and a light-emitting layer that is provided on the substrate and that receives an electron beam and generates ultraviolet light. The light-emitting layer comprises an oxide polycrystal (a Pr:LPS crystal or a Pr:LSO crystal, for example) that is in powder or granular form, that has an activator added thereto, and that contains Lu and Si.
