Abstract
A red phosphor for a plasma display panel (PDP) including (Y,Gd)Al.sub.3(BO.sub.3).sub.4:Eu.sup.3+, a paste composition including the same and a plasma display panel including a phosphor layer made out of the red phosphor. The red phosphor for a plasma display panel can have reduced decay time by using (Y,Gd)Al.sub.3(BO.sub.3).sub.4:Eu.sup.3+ alone or as a main constituent in a combination with (Y,Gd)BO.sub.3:Eu.sup.3+. In addition, in a plasma display panel (PDP) including a phosphor layer made out of the red phosphor, by reducing the decay time of the PDP, coloring properties thereof can be improved and luminance saturation thereof at a high gradation degree occurring when Y(V,P)O.sub.4:Eu.sup.3+ is used to improve color coordinates can be prevented.
