Synthesis of wurtzite ZnS nanorods by microwave assisted chemical route

ZnS nanorods were synthesized by microwave assisted chemical method. Polyvinylpyrrolidone (PVP) was used as a capping agent to stabilize the nanostructure. Synthesized ZnS nanorods were characterized by X-ray diffraction (XRD), Energy dispersive X-ray analysis (EDAX), Transmission Electron Microscopy (TEM), UV–visible spectrophotometry (UV), photoluminescence spectroscopy (PL) and Fourier transform Infra-red spectroscopy (FTIR). The results showed that the nanorods have wurtzite phase crystal structure and exhibits near band edge luminescence in the ultra violet region. The diameter of the synthesized PVP capped ZnS nanorods is about 600 nm. The possible growth mechanism of the ZnS nanorods could be attributed to the oriented attachment effect.

► Wurtzite ZnS nanorods were synthesized by microwave assisted chemical method.
► Monodispersity have been achieved by inexpensive route.
► PVP played a determinative role in the formation of ZnS nanorods.
