Abstract

See full text

An ultraviolet light generating target 20 includes a substrate 21 made of sapphire, quartz or rock crystal; and a Pr:LuAG polycrystalline film 22, provided on the substrate 21, that generates ultraviolet light upon receiving an electron beam. By using a Pr:LuAG polycrystal as the target, the ultraviolet light generating efficiency can be increased more remarkably than when a Pr:LuAG single crystal film is used.
