Abstract
Fluorescent materials and preparation methods thereof are provided. The fluorescent materials are represented by the general formula: M, ZnAlO and YO: Re, wherein Re is at least one selected from Eu and Tb, M is at least one selected from Ag, Au, Pt and Pd in the form of nano-particle, and 0<×≦0.05. The said methods include the following steps: step, preparing a colloid of ZnAlO; step, preparing a colloid of Y and Re containing the metal element M; step, mixing the colloid of ZnAlO with the colloid of Y and Re, aging and heating treatment to form the fluorescent materials. Compared to the YOfluorescent materials in the art the present fluorescent materials have higher luminescence efficiency, conductivity, long life and industrial applicability.
