Target for ultraviolet light generation, electron beam-excited ultraviolet light source, and production method for target for ultraviolet light generation

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.

Fluorescent pastes and films

A fluorescent paste that can form a fluorescent film and can be manufactured without a binder resin and has a high recording density and peel resistance. Fluorescent fine particles each coated with a film formed of a film compound having a reactive group and a curing agent having a plurality of crosslinking reaction groups each reacting with the reactive group to form bonds are blended with a solvent to manufacture fluorescent paste. The fluorescent paste is applied to a substrate coated with a film formed of a second film compound having a second reactive group and is cured by crosslinking reactions between the reactive group and the second reactive group, and the crosslinking reaction groups to form a fluorescent film.
