Synthesis and photoluminescence property of Sn-doped ZnO nanobelts

Sn-doped ZnO nanobelts were successfully synthesized via thermal evaporation method.XRD results confirm that the products are the wurtzite structure of ZnO.EDS analyse shows that the content of Sn in the doped ZnO nanobelts is around 5at%.XPS results reveal that Sn element exists as Sn4+.Room temperature PL spectrum shows that there is only one emission peak centered at 445.8nm.The luminescence mechanism of the Sn-doped ZnO nanobelts was also discussed.
