Synthesis of hollow nanosphere Sb2Te3 via a thermal evaporation process

Hollow nanosphere antimony telluride (nano-Sb2Te3) was fabricated with antimony (Sb) and telluride (Te) vapors via a fast and facile a thermal evaporation process. The average size of nano-Sb2Te3 is about 50–80 nm with the wall thickness of about 10 nm. XRD test indicates that the as-prepared Sb2Te3 hollow nanospheres are well crystallized. And Raman studies show the precipitation of Te from Sb2Te3 under a relative high laser power. The present study offers a fast way for synthesis of nanostructure compounds, which may have scientific and technological applications in various fields.
