BaY1.94-xAl4SiO12:0.06Ce3+, xPr3+ (x = 0, 0.01, 0.02, 0.03 and 0.04) phosphors were successfully prepared via the solid-state synthesis method at 1450degC. The diffuse reflection spectra, emission spectra, thermal luminescence stability of the phosphors and the optical properties of the white LEDs fabricated by employing the phosphors were investigated. BaY1.94-xAl4SiO12:0.06Ce3+, xPr3+ phosphors can be effectively excited by blue light. Excited by 450 nm, the emission intensity located at 613 nm of BaY1.94-xAl4SiO12:0.06Ce3+, xPr3+ phosphor significantly increases as the Pr3+ concentration increases, and the maximum intensity is reached at x = 0.02, but the luminescence intensity located at 540 nm of BaY1.94-xAl4SiO12:0.06Ce3+, xPr3+ phosphor decreases as the concentration of Pr3+ increases. The Ra value of the white LED fabricated by employing BaY1.92Al4SiO12:0.06Ce3+, 0.02Pr3+ as yellow phosphor was better than that of the white LED made by using BaY1.94Al4SiO12:0.06Ce3+. All the experimental results demonstrate that the red region of the emission spectrum of BaY1.94Al4SiO12:0.06Ce3+ phosphor could be effectively improved by co-doping Pr3+, however, the emission intensity and thermal quenching performance will be slightly weakened.
