Sb3+-doped YBO3 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 YBO3 phosphors were investigated. The YBO3 crystals from the hydrothermal system look like flowers, whereas those from the solid-state process look like some agglomerates of little spheres. The Sb3+-doped YBO3 powders prepared via both methods showed the blue emission with the peak at around 452 nm, which corresponds to the 3P1→1S0 transition of Sb3+ ions. However, the emission intensity of the Sb3+-doped YBO3 from the hydrothermal system is about 3.5 times as much as that from the solid-state process. The (Sb3+,Eu3+) co-doped YBO3 crystals were also prepared through the two methods. The results showed that the emission intensity of Sb3+ ions in (Sb3+, Eu3+) co-doped YBO3 synthesized by the hydrothermal method is stronger than that by the solid-state process.
