Sb2MoO6, Bi2MoO6, Sb2WO6, and Bi2WO6 flake-like crystals: Generalized hydrothermal synthesis and the applications of Bi2WO6 and Bi2MoO6 as red phosphors doped with Eu3+ ions

- Sb2MoO6, Bi2MoO6, Sb2WO6, Bi2WO6 are controllably prepared.
- Dosage of NaOH in solution plays crucial role in determining the products.
- Orthorhombic Sb2O3 and tetragonal Bi12O17Cl2 also occur.
- Bi2WO6 and Bi2MoO6 are doped with Eu3+ ions to prepare red phosphors.
