This paper describes an ethylene glycol(EG)-assisted approach to the ultralong Sb2S3 nanowires,formed by a simple hydrothermal reaction between SbCl3 and Na2S in the presence of distilled water.Transmission electron microscopy and scanning electron microscopy studies indicate that these Sb2S3 nanowires possess a diameter around 200 nm and length up to 100 μ m.High-resolution transmission electron microscopy and selected area electron diffraction studies reveal that each Sb2S3 nanowire is a single-crystal along the [001] direction.The possible formation mechanism of the nanowires was discussed.The effects of volume ratio of ethylene glycol/water on the morphology of Sb2S3 nanowires were also investigated.Diffuse reflectance spectrum result shows that the final products have an apparent blue shift by quantum size effect.

Transmission electron microscopy and scanning electron microscopy studies indicate that these Sb2S3 nanowires possess a diameter around 200 nm and length up to 100 μm. High-resolution transmission electron microscopy and selected area electron diffraction studies reveal that each Sb2S3 nanowire is a single-crystal along the [001] direction. possible combination mechanism of the nanowires was discussed . The effects of volume ratio of ethylene glycol / water on the morphology of Sb2S3 nanowires were also investigated. Diffuse reflectance spectrum result shows that the final products have an apparent blue shift by quantum size effect.
