Abstract

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.
