| Abstract | We report the cathodoluminescence and aging properties of a series of green phosphors of formula Sr1-xMxGa2S4:Eu (x = 0.0-1.0, M = Ba or Ca) that have potential applications in field emission displays (FEDs). The series of phosphors was synthesized via NaBr-aided solid-state reactions in a flowing H2S stream. A low level (~20%) of Ba or Ca substitution for Sr in SrGa2S4:Eu maintains the orthorhombic phase of pure SrGa2S4:Eu phosphors. Further, a low level (~20%) of Ba or Ca substitution for Sr in SrGa2S4:Eu provides various green colors and sufficient brightness for FED applications. Substitution of Ba or Ca for Sr in SrGa2S4:Eu also improved the stability of the phosphor when it was operated under electron-beam irradiation of 5 kV. |
