We have synthesized a Eu2+-activated lanthanide co-doped Sr3SiO5 : Eu yellow-orange phosphor. In this experiment, sample powder has been synthesized by conventional solid state method. It was calculated that luminescent efficiency of a Gd3+ co-doped Sr3SiO5:Eu phosphor sample is up to 105% than that of only Sr3SiO5:Eu phosphor. Those samples can be applied such as phosphor for white LED lamps through integrating on the UV or blue chips. On the contrary, the use of a Dy, Ce, Pr and lanthanide short of Gd by the co-doping materials was caused by decreasing luminescent intensity. The emission band was shifted from 572nm to short wavelengths by co-doping lanthanide. The emission band of a Nd3+ co-doped Sr3SiO5 : Eu phosphor sample was not symmetrical at 570nm. As Nd3+ concentration increased, two emission bands were observed
