Abstract
- ZnS nanoribbons with variable widths ranging from a few nanometres to micrometre orderhave been fabricated in a controlled way. The ultra-long nanoribbons were singlecrystalline, smooth and uniform throughout their lengths. Growth of the nanoribbons wasinitiated by the vapour–liquid–solid process and subsequently their widths wereregulated by the influence of the vapour–solid process. These nanoribbons possesseda bulk-like bandgap as determined from the optical absorption spectra. Roomtemperature photoluminescence was observed in the UV–visible region from theZnS nanoribbons with the emission peaks at 398 and 458 nm attributed to thetransitions from the sulfur vacancy related defect states and surface states respectively.
