摘要：
Low voltage green phosphor, ZnGa2O4:Mn, powder was prepared at high temperature more than 900 degrees C in Ar or vacuum. From compositional analysis, it was confirmed that the concentration of oxygen decreased about 13% in ZnGa2O4:Mn phosphor sintered in vacuum but not in Ar. It induces the deficiency of oxygen content in the phosphor. It means that this oxygen lacks result in the formation of the energy level near 513 nm which contributes to the improvement of the brightness of ZnGa2O4:Mn.
