Sr3SiO5: Ce3+, Li+phosphors were prepared by solid-state reaction. By co-doping Ba2+into them, the emission band of the phosphors showed a red shifts with a broad emission band peaking at 590nm. The InGaN-based 0.35Ba2+co-doped Sr3SiO5: 0.018Ce3+, 0.018Li+LED presented white emitting and color rendering index of 88.
