Abstract

Low voltage green phosphor, ZnGa₂O₄:Mn, powder was prepared at high temperature more than 900 °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.
