Controllable synthesis of CdWO4 nanorods and nanowires via a surfactant-free hydrothermal method

摘要

Single-crystalline CdWO₄ nanorods and nanowires have been controllably synthesized via a simple surfactant-free hydrothermal route. The obtained samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and electron diffraction (ED). The results showed that the starting material played a crucial role in the controllable preparation of CdWO₄ nanorods and nanowires. The synthesis mechanism was also discussed.
