Material characterizations of ZnO/ZnS core-shell structures on glass substrate

ZnO/ZnS core-shell nanostructures were hydrothermally fabricated on glass substrates. Multiple material characterizations were used to examine the nanostructures. Results indicate that a ZnS shell with a thickness around 10 nm could be viewed on the ZnO/ZnS core-shell structures. Furthermore, different crystalline phases and element compositions in different locations around nearby nanostructures could be found in selected area diffraction patterns and energy dispersive X-ray spectroscopy. ZnS/ZnO nanostructures on glass substrates show promise for future optoelectronic and electronic device applications.
