Abstract
Silicate luminescent materials and preparation methods thereof are provided. The luminescent materials are represented by the general formula: MMSiO:xCe, yM, Mis at least one selected from Ca, Sr, Ba, Mg and at least contains Ca, Mis Sc, Sc and Y, Mis one selected from metal nano particles of Ag, Au, Pt, Pd or Cu, wherein 2.8≦a≦3.2, 1.8≦b≦2.1, 2.9≦c≦3.3, 0.01≦x≦0.2 and 1×10≦y≦1×10. Compared to the luminescent materials in the prior art, the said luminescent materials have higher luminous efficiency and more stable performance and structure. The said methods have simple technique and low cost, therefore are appropriate to be used in industry.
