Title:
ULTRAVIOLET LIGHT GENERATING TARGET, ELECTRON-BEAM-EXCITED ULTRAVIOLET LIGHT SOURCE, AND METHOD FOR PRODUCING ULTRAVIOLET LIGHT GENERATING TARGET
Document Type and Number:
WIPO Patent Application WO/2012/147743
Kind Code:
A1
Abstract:
An ultraviolet light generating target (20) is provided with: a substrate (21) comprising sapphire, quartz, or rock crystal; and a Pr:LuAG polycrystalline film (22) that is provided on the substrate (21) and that generates ultraviolet light by receiving an electron beam. It is possible to significantly increase ultraviolet light generation efficiency compared to when using a Pr:LuAG monocrystalline film by means of using Pr:LuAG polycrystals as the target.
