ULTRAVIOLET LIGHT GENERATING TARGET, ELECTRON BEAM EXCITING ULTRAVIOLET LIGHT SOURCE, AND PROCESS OF MANUFACTURING ULTRAVIOLET LIGHT GENERATING TARGET

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet light generating target capable of enhancing ultraviolet light generation efficiency, an electron beam exciting ultraviolet light source, and process of manufacturing the ultraviolet light generating target.;SOLUTION: An ultraviolet light generating target 20 includes: a UV-light transmitting substrate 21; a light-emitting layer 22 that is provided on the substrate 21 and generates ultraviolet light UV by receiving an electron beam EB. The light-emitting layer 22 contains a powder type or granular oxide crystal, for instance, a Pr:LPS crystal or a Pr:LSO crystal, added with an activator, containing Lu and Si.;COPYRIGHT: (C)2014,JPO&INPIT
