Abstract
Metal nano particles doped with silicate luminescent materials and preparation methods thereof are provided. The luminescent materials are represented by the general formula: (SrAEu)SiO:Dz@M, wherein A is one or two selected from alkaline-earth metal elements, D is F or Cl, @ is for coating, M is one or two selected from Ag, Au, Pt, Pd or Cu metal nano particles, 0≦x≦0.5, 0.001<y≦0.15, and 0≦z≦0.5. n is a molar ratio of metal nano particles to the silicon element, wherein 0<n≦0.01. Compared to the luminescent materials in the art, the said luminescent materials have higher internal quantum efficiency, luminous intensity and stability, therefore they are appropriate to be used in coating technique and improve the visual effect.
