摘要：

TeO2 nanowires were synthesized on Au-coated glass substrates at 450℃ by thermal evaporation method using Te powders as the source material. The structures and morphology of TeO2 nanowires were characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. A possible growth mechanism was proposed. The results showed that TeO2 nanowires with a tetragonal structure were approximately 70~200 nm in diameter and several hundreds of micrometers to 2 mm in length. By the morphology observation of the as-prepared products obtained at different growth times, the growth process of TeO2 nanowires was analyzed. It is concluded that the growth of TeO2 nanowires is based on vapor-solid growth mechanism, where Au film deposited on the glass substrates is possibly used for inducing and accelerating the growth of TeO2 nanowires. © 2016, Editorial Department of Journal of Northeastern University.
