| Abstract: | Dy3+ doped zirconia with monoclinic and tetragonal crystal structures were prepared by a sol-gel method with ammonia. The influences of sintering time, reaction temperature and the concentration of Dy3+ on the structure of the zirconia were investigated. The photoluminescence properties of Dy3+ in zirconia with different structures were comparatively studied. Results show that Dy3+ ion could perform as luminescent probe to study the crystal structure of zirconia by different splitting of emission peaks. |
