Preparation of ZnS Nanofibers Via Electrospinning
Abstract:Using an electrospinning technique coupled with a thermal treatment approach, ZnS nanofibers have been prepared by sulfurizing the electrospun ZnO nanofibers (as a template) at 500°C in an H2S atmosphere. The ZnS nanofibers, with a zinc-blende structure, were found to be rough and uneven, which was considered to be correlated with the processing conditions. Band gap characteristic peaks mainly centered at 390 and 445 nm have been observed, corresponding to the purple and blue emission, respectively. The method demonstrated here could be a general approach of fabricating other one-dimensional-nanostructured sulfides for potential applications in nanoscale devices.
