The BaZr0.2Si2O5.4: Eu2+/Eu3+ phosphors were prepared with different concentrations of Eu2O3 by a self-reduction method under air condition. The X-ray diffraction and the photoluminescence properties of the prepared samples were analyzed. The emission spectra consisting of a broadband emission from the 4f →5d transitions of Eu2+ and sharp emissions from 5D0-7FJ (J = 0, 1, 2, 3, 4) transitions of Eu3+ are observed. The different luminescent colors can be obtained and modulated by doping different concentrations of Eu2O3 and the white light emission can be observed as the concentration of europium is 6%.
