“…Liu et al [26] obtained TeO 2 nanowires by a thermal evaporation method of pure Te metal in a muffle furnace at 300-500 • C. The nanowires were about tens of microns in length and 30-200 nm in diameter. Jiang et al [32] synthesized tellurium oxide nanorods by the laser ablation of elemental tellurium on the glass substrate in a hot air atmosphere. The nanorods were 20-80 nm in diameter to several microns long.…”

“…Despite the long body of experimental work on t -Te nanostructures, only few studies have been focused on the growth of TeO 2 NWs. The first growth of TeO 2 NWs was achieved through heating Te nanostructures, in the presence of oxygen, at high temperature (500°C) for about 20 min22. TeO 2 NWs were found to exhibit room temperature gas sensing properties2324 and enhanced luminescence when covered by a layer of ZnO25.…”

One dimensional (1D) nanostructures of semiconducting oxides and elemental chalcogens culminate over the last decade in nanotechnology owing to their unique properties exploitable in several applications sectors. Whereas several synthetic strategies have been established for rational design of 1D materials using solution chemistry and high temperature evaporation methods, much less attention has been given to the laser-assisted growth of hybrid nanostructures. Here, we present a laser-assisted method for the controlled fabrication of Te nanotubes. A series of light-driven phase transition is employed to controllably transform Te nanotubes to core-Te/sheath-TeO2 and/or even neat TeO2 nanowires. This solid-state laser-processing of semiconducting materials apart from offering new opportunities for the fast and spatially controlled fabrication of anisotropic nanostructures, provides a means of simultaneous growing and integrating these nanostructures into an optoelectronic or photonic device.

“…Recent research in materials science has focused on preparing nanorods of either TeO 2 or Te(0) by using physical/chemical techniques, such as high-energy sources (e.g., laser ablation) run at high temperatures (e.g., 500°C), sonication, or auto-oxidation of highly reactive chemicals (e.g., NaHTe) with oxygen (9,15,47). We suggest that the use of Te-respiring anaerobes may also yield a diversity of useful Te nanomaterials that can be generated at room temperature and without requiring the use of either harsh chemical or physical methods.…”

Certain toxic elements support the metabolism of diverse prokaryotes by serving as respiratory electron acceptors for growth. Here, we demonstrate that two anaerobes previously shown to be capable of respiring oxyanions of selenium also achieve growth by reduction of either tellurate [Te ( , which cluster together, forming larger (ϳ1,000-nm) rosettes composed of numerous individual shards (ϳ100-nm width by 1,000-nm length). In contrast, Sulfurospirillum barnesii forms extremely small, irregularly shaped nanospheres (diameter < 50 nm) that coalesce into larger composite aggregates. Energy-dispersive X-ray spectroscopy and selected area electron diffraction indicate that both biominerals are composed entirely of Te and are crystalline, while Raman spectroscopy confirms that they are in the elemental state. These Te biominerals have specific spectral signatures (UV-visible light, Raman) that also provide clues to their internal structures. The use of microorganisms to generate Te nanomaterials may be an alternative for bench-scale syntheses. Additionally, they may also generate products with unique properties unattainable by conventional physical/chemical methods.
