Sr<sup>3</sup>SiO<sup>5</sup>: Ce<sup>3+</sup>, Li<sup>+</sup>phosphors were prepared by solid-state reaction. By co-doping Ba<sup>2+</sup>into them, the emission band of the phosphors showed a red shifts with a broad emission band peaking at 590nm. The InGaN-based 0.35Ba<sup>2+</sup>co-doped Sr<sup>3</sup>SiO<sup>5</sup>: 0.018Ce<sup>3+</sup>, 0.018Li<sup>+</sup>LED presented white emitting and color rendering index of 88.
