Yttrium oxide phosphor mixture and preparation method thereof |
摘要 |
Fluorescent materials and preparation methods thereof are provided. The fluorescent materials are represented by the general formula: M, Zn1-xAlxO and Y2O3: 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 1, preparing a colloid of Zn1-xAlxO; step 2, preparing a colloid of Y and Re containing the metal element M; step 3, mixing the colloid of Zn1-xAlxO with the colloid of Y and Re, aging and heating treatment to form the fluorescent materials. Compared to the Y2O3 fluorescent materials in the art the present fluorescent materials have higher luminescence efficiency, conductivity, long life and industrial applicability. |
