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MSi2N2O2:Eu2+(M=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,SrSi2N2O2:Eu2+的发射主峰位于541 nm,属于黄绿光发射;BaSi2N2O2:Eu2+的发射主峰位于492 nm,属于蓝绿光发射。BaSi2N2O2:Eu2+的电流饱和性能要比SrSi2N2O2:Eu2+好。但在相同电流密度的激发下,SrSi2N2O2:Eu2+的发光强度明显高于BaSi2N2O2:Eu2+,因此,SrSi2N2O2:Eu2+更适合应用于FED中。A series of new FED（Field Emission Display） green phosphors of MSi2N2O2：Eu2＋（M=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,SrSi2N2O2：Eu2＋ emits yellow green light with the peak at 541 nm,and BaSi2N2O2：Eu2＋ shows a blue-green emission dominates at 492 nm.The current saturation character of BaSi2N2O2：Eu2＋ is better than that of SrSi2N2O2：Eu2＋.While,under the excitation of the same current density,the luminescence intensity of SrSi2N2O2：Eu2＋ is much higher than that of BaSi2N2O2：Eu2＋.So,SrSi2N2O2：Eu2＋ is more suitable for FED application.
