摘要

采用高温固相法合成了一系列新型绿色FED(Field Emission Display)荧光粉

∶ Eu

(

=Sr

Ba)

研究了该荧光粉在不同电压和电流密度下的发光特性。在电子束激发下

SrSi

∶ Eu

的发射主峰位于541 nm

属于黄绿光发射;BaSi

∶ Eu

的发射主峰位于492 nm

属于蓝绿光发射。BaSi

∶ Eu

的电流饱和性能要比SrSi

∶ Eu

好。但在相同电流密度的激发下

SrSi

∶ Eu

的发光强度明显高于BaSi

∶ Eu

因此

SrSi

∶ Eu

更适合应用于FED中。

Abstract

A series of new FED (Field Emission Display) green phosphors of

∶ Eu

(

=Sr

Ba) are synthesized by solid state reaction

and their luminescence properties under the excitation of different voltage and current density are studied. Under the excitation of electron beams

SrSi

∶ Eu

emits yellow green light with the peak at 541 nm

and BaSi

∶ Eu

shows a blue-green emission dominates at 492 nm. The current saturation character of BaSi

∶ Eu

is better than that of SrSi

∶ Eu

. While

under the excitation of the same current density

the luminescence intensity of SrSi

∶ Eu

is much higher than that of BaSi

∶ Eu

. So

SrSi

∶ Eu

is more suitable for FED application.
