    Abstract: Disclosed is a low voltage blue emitting phosphor and a method for producing the same including the steps of: mixing ZnO, Ga2O3and a Na-based compound to obtain a mixture material; sintering the material at a temperature of 1100 to 1300° C.; milling the first sintered material; washing the milled material using hydrochloric acid; sintering the washed material at a temperature of 800 to 1100° C.; and classifing the material. The low voltage blue emitting phosphor produced as described above is a ZnO—Ga2O3matrix doped with Na, and has an x value of 0.18±0.05 and a y value of 0.17±0.05 in a CIE chromaticity diagram.
