摘要：
Novel phosphor systems are disclosed having the formula A2SiO4:Eu2+D, where A is at least one of a divalent metal selected from the group consisting of Sr, Ca, Ba, Mg, Zn, and Cd; and D is a dopant selected from the group consisting of F, Cl, Br, I, P, S and N. In one embodiment, the novel phosphor has the formula (Sr1-x-yBaxMy)2 SiO4:Eu2+F (where M is one of Ca, Mg, Zn, or Cd in an amount ranging from 0
