Abstract
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.
