Synthesis of tellurium nanorods via spontaneous oxidation of NaHTe at room temperature

Trigonal phase of tellurium (t-Te) nanorods with tapered ends have been synthesized through spontaneous oxidation of NaHTe by dissolved oxygen at room temperature. Utilization of sodium dodecyl benzenesulfonate was found to help to obtain high-quality nanorods. The product was characterized by X-ray diffraction and Transmission electron microscopy. In addition, the possible nucleation and growth mechanism of the t-Te nanorods was discussed. (C) 2004 Elsevier B.V. All rights reserved.
