Semimetal Bi and Sb thin films with novel hierarchical structures were synthesized on zinc substrate via a hydrothermal method. X-ray diffraction (XRD) analysis confirmed the formation of pure semimetals Bi and Sb. Scanning electron microscopy images showed that Bi films constructed with microtube arrays and hierarchical microspheres can be obtained selectively by altering the concentration of Bi3+ions. The synthesized Sb films were constructed with bowl-shaped particles. The growth process ofdoi:10.1155/2015/581486 fatcat:xqxyxd5ghbfjxlkh5bgm3hsinq
