| Abstract: | Multiwalled carbon nanotube (MWCNT)/CdS core/shell heterostructures have been successfully synthesized via a simple solution-phase method. The thickness of CdS shells can be facilely tuned by either the reaction temperature or time. The CdS nanoparticles are first formed directly on the surface of MWCNT, and then a uniform CdS sheath is yielded via orientated aggregation processes. The present work provides a simple route to obtain MWCNT-based core/shell heterostructures and thus is of wide interest for the studies of nanomaterials and nanodevices. |
