| Abstract: | By solid-state synthesis method, Ho3+/Yb3+ co-doped CeO2-ZrO2 nano-powders have been prepared. The concentration of Ce4+ ions has greater effect to the oxygen lattice structure. When the concentration of Ce4+ ions is 30 mol%, the oxygen lattice is a tetrahedral space group and the luminescence intensity of the sample is strongest. The results show that the lattice structure can be changed by inducting the Ce4+ ions into Ho3+/Yb3+ co-doped ZrO2. And the emission character can be improved. |
