摘要：
Fluorescent materials and preparation methods thereof are provided. The fluorescent materials are represented by the general formula: Y 2 O 3 : Re, M, Zn 1-x Al x O, 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 1-x Al x O; step 2, preparing a colloid of Y and Re containing the metal element M; step 3, mixing the colloid of Zn 1-x Al x O with the colloid of Y and Re, aging and heating treatment to form the fluorescent materials. Compared to the Y 2 O 3 fluorescent materials in the art the present fluorescent materials have higher luminescence efficiency, conductivity, long life and industrial applicability.
