Controllable synthesis of corrugated CdS nanoribbons of high quality by vapor–liquid–solid method
High-quality corrugated CdS nanoribbons were synthesized through thermal evaporation of CdS powder (1.44 g). The length of periodicity could be tuned simply by varying the deposition temperature. Also, when the CdS source was reduced to 0.144 g, the product was slick nanobelts. The hexagonal wurtzite phase and single crystallinity of products were verified by XRD and SAED, respectively. The mechanism for the growth of nanoribbons has been described. In photoluminescence studies, a sharp peak due to near-band-edge emission and a broad band due to surface-trapped states or Cd vacancy emission were observed. CdS nanoribbons with corrugated structures have not been reported before and their presence makes the investigation of CdS nanostructures more interesting and intriguing.
