More Information
Summary:A target for ultraviolet light generation comprises a substrate adapted to transmit ultraviolet light therethrough and a light-emitting layer disposed on the substrate and generating ultraviolet light UV in response to an electron beam. The light-emitting layer includes a powdery or granular rare-earth-containing aluminum garnet crystal doped with an activator. The light-emitting layer has an ultraviolet light emission peak wavelength of 300 nm or shorter.
