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 (In<SUB>1-x-y-z</SUB>Gd<SUB>y</SUB>Y<SUB>z</SUB>)BO<SUB>3</SUB>:Tb<SUB>x</SUB>, 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 (In<SUB>1-x-y-z</SUB>Gd<SUB>y</SUB>Y<SUB>z</SUB>)BO<SUB>3</SUB>:Tb<SUB>x</SUB>, where 0<x<=0.5 and 0<y<=0.5, 0<=z<=0.5 and 1-x-y-z>0. |
