摘要

等离子体平板显示用绿色发光粉主要有硅酸盐(Zn

SiO

:Mn

)、铝酸盐(BaAl

:Mn

)、磷酸盐(YPO

:Tb

)和硼酸盐(YBO

:Tb

)4种体系。前两者具有量子效率高、色纯度好等优点

然而抗真空紫外辐照能力差

发光衰减时间长;Tb

激活的磷酸盐和硼酸盐体系具有适宜的发光寿命

抗真空紫外辐射能力强

然而Tb

的发射光是黄绿色

色纯度不够好

且发光亮度相对较弱。按一定的混合比率使BaAl

:Mn

和YPO

:Tb

均匀混合

组合这两种体系绿色发光粉各自的优点

优化了等离子体平板显示用绿色发光粉的整体性能。

Abstract

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

:Mn

YPO

:Tb

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

:Mn

and YPO

:Tb

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