| 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. |
