Abstract
For the first time the infrared absorbance of the ultrasonically fabricated nanowires of antimony sulfoiodide (SbSI) has been measured from 750 cm−1 to 4000−1 cm. The SEM and HRTEM investigations exhibit that the as-prepared SbSI ethanogel is made up of large quantity nanowires with diameters of about 10–50 nm and lengths reaching up to several μm and single-crystalline in nature. The IR measurements have been performed on as-prepared, dried and postannealed samples. The obtained results have been compared with the results of IR investigations of powdered single crystals of SbSI. One of the features of the sonochemically fabricated SbSI nanowires is the strong adsorption of ethanol, ethoxide species, ethylene and water.
