The research on Plasma display panel (PDP) phosphors has gained much attention. The green PDP phosphor is an important component due to its highest brightness in three-color-based phosphors. Existing and developing green-emitting phosphors include Mn-activated silicates and aluminates
and Tb-activated phosphates and borates systems. Mn-activated silicates and aluminates have high quantum efficiency and excellent color coordinate
but low stability to vacuum ultraviolet (VUV) radiation and long decay time. Tb-activated phosphates and borates have suitable decay time and high stability to VUV radiation
but low brightness and color purity. This work investigates the luminescent performance of single BaAl

and especially their blends. The result indicates that the blends of BaAl

can effectively combine their respective advantages to improve the overall luminescent performance of green-emitting phosphors for PDP application.
