An inorganic phosphor and a method for manufacturing the same are proposed. The sol-gel method is used and the elements vanadium and sulfate are added to synthesize a red-emission gadolinium titanium oxide phosphor doped with Eu3+, V and S to change the original red/orange-emission property and enhance the red-emission intensity. Moreover, the elements vanadium and sulfate replace the rare-earth Eu3+ element as active sites to obtain a white-emission gadolinium titanium oxide phosphor doped with V and S. Using this single-kind phosphor, white light can be emitted under the excitation of violet light without the need of mixing multiple colors.
