Abstract :
The degradation behavior of ZnGa2O3.994Se0.006: Li, Mn caused by thermal annealing and acceleration voltage was investigated. Thermal degradation of ZnGa2O3.994Se0.006: Li, Mn initiated from the volatilization of Se, whereas, commercial green phosphor, ZnS: Cu, Al, transformed from ZnS to ZnO. The cathodoluminescence measurements showed that the saturation characteristics of the luminance of ZnGa2O3.994Se0.006: Li, Mn at higher voltage were a little better than that of commercial green phosphor (ZnS: Cu, Al). These results indicate that the phase stability of ZnGa2O3.994Se0.006: Li, Mn in both thermal and acceleration voltage dependent degradations is superior to that of ZnS: Cu, Al.
