Abstract
Sb -doped YBO crystals were prepared through a low-temperature hydrothermal method and a high-temperature solid-state technique, respectively. The effects of preparation methods on the morphologies and luminescent properties of YBO phosphors were investigated. The YBO crystals from the hydrothermal system look like flowers, whereas those from the solid-state process look like some agglomerates of little spheres. The Sb -doped YBO powders prepared via both methods showed the blue emission with the peak at around 452 nm, which corresponds to the P → S transition of Sb ions. However, the emission intensity of the Sb -doped YBO from the hydrothermal system is about 3.5 times as much as that from the solid-state process. The (Sb ,Eu ) co-doped YBO crystals were also prepared through the two methods. The results showed that the emission intensity of Sb ions in (Sb , Eu ) co-doped YBO synthesized by the hydrothermal method is stronger than that by the solid-state process.
