Hydrothermal synthesis of Sb2O3 nanorod-bundles via self-assembly assisted oriented attachment

► We report the fabrication of uniform Sb2O3 nanorod-bundles via a facile hydrothermal synthetic method. ► Morphology, composition, microstructure and optical property of Sb2O3 nanorod-bundles were researched. ► The self-assembly assisted oriented attachment mechanism was proposed.
