Abstract: A plasma display wherein all the charges are positive is disclosed which comprises a green phosphor which hardly adsorbs or reacts with water, carbon monoxide, a carbon dioxide gas or a hydrocarbon. A green phosphor layer is made of a green phosphor composed of at least one material selected among those represented by the general formula M1-a(Ga1-xAlx)2O4:Mna (wherein M is Zn, Mg, Ca or Sr); the general formula (Y1-a-yGda)(Ga1-xAlx)3(BO3)4:Tby; the general formula (Y1-a-yGda)(Ga1-xAlx)3(BO3)4:Cey, Tby; the general formula (Y1-a-yGda)BO3:Tby; or the general formula (Y1-a-yGda)3(Ga1-xAlx)5O12:Tby.

Abstract: The steps of weighing, mixing and filling for phosphor powder are followed by the reducing atmosphere treating step wherein treating in a reducing atmosphere is carried out at least once and, after the reducing atmosphere treating step, pulverization, dispersion, water washing and drying and further the oxygen ion implantation treating step wherein oxygen ion implantation and annealing are performed, so that host crystals are restored with respect to oxygen defects.
