摘要：The present invention discloses a fluorescent substance for low voltage excitingsource, wherein the host lattice of the fluorescent substance is composed of metal ionsand silica, and the host lattice is further doped with activator. Furthermore, the generalformula of the fluorescent substance is (SrMEu)SiO(x≧0, y>0, x+y<2), wherein Mcomprises at least one kind of metal ion except Sr or Eu. The wavelength of the lightemitted from the fluorescent substance can be shifted by introducing M into the latticestructure, so that the provided fluorescent substance is able to emit lights with variouscolors from yellow to yellow-green. Additionally, the provided fluorescent substancewith single phase can be fabricated in a variety of methods, such as solid state reactionmethod, co-precipitation method, gel method and micro emulsion method.
