ABSTRACT:
The invention relates to a plasma display screen comprising a carrier plate, a transparent front plate, a ribbed structure which divides the space between the carrier plate and the front plate into plasma cells that are filled with a gas, one or more electrode arrays to generate corona discharges in the plasma cells, and a phosphor layer which comprises a phosphor selected from the group composed of doped terbium(III)-activated phosphors of the general formula (In1-x-y-zGdyYz)BO3:Tbx, where 0<x≦0.5 and 0<y≦0.5, 0≦z≦0.5 and 1-x-y-z>0. The invention also relates to a phosphor selected from the group composed of doped terbium(III)-activated phosphors of the general formula (In1-x-y-zGdyYz)BO3:Tbx, where 0<x≦0.5 and 0<y≦0.5, 0≦z≦0.5 and 1-x-y-z>0.
