| Abstract
| - Orthorhombic Bi2S3 (bismuthinite) nanorods and nanowires are synthesized by the solventlessthermolysis of bismuth alkylthiolate precursors. Reactions carried out in air at ∼225 °C in the presenceof a capping ligand species, octanoate, produce high aspect ratio (>100) nanowires. Lower aspect rationanowires (∼7) are produced by the same approach with the addition of elemental sulfur at lower reactiontemperature (∼160 °C). Both the nanowires and nanorods are oriented with their long axes in the [002]crystallographic direction. Higher reaction temperatures (∼250 °C) produce crossed nanowire networks,or fabrics, with highly oriented growth as a result of heterogeneous nanowire nucleation and epitaxialelongation off the surface of existing wires.
- Crystalline Bi2S3 nanorods and nanowires were produced using a solventless synthesis. The aspect ratio depends on the sulfur source: the thermolytic decomposition of bismuth thiolate molecular precursor gives nanowires, whereas the addition of elemental sulfur gives nanorods. At higher reaction temperatures, crossed nanowires formed with epitaxial interfacingtermed “nanofabric”.
