ABSTRACT:
A green-light-emitting rare gas discharge lamp includes a glass tube filled with at least one selected from the group consisting of xenon, neon, helium, argon and krypton as a rare gas capable of emitting vacuum ultraviolet rays of a wavelength of not more than 200 nm, and includes on an inner surface of the glass tube a layer of a green-light-emitting phosphor having terbium-activated yttrium silicate, whereby it is intended to obtain enhanced performance as a green-light-emitting light source and to put the discharge lamp to practical use as a green-light-emitting light source for office automation equipment, for instance.
