    Abstract: Zinc sulfide (ZnS) of wurtzite structure nanotowers with a ZnO core has been grown using a simple catalyst-free thermal evaporation technique. The ZnS nanotowers are as long as to several tens of micrometers. The high-magnification TEM image of a single nanotower reveals clear ZnS/ZnO interface. The ZnO core is likely formed at the first stage due to the residual O2. The PL spectrum indicates that the nanotowers have a visible emission peak centered at 409 nm.
