00925njm 22002777a 4500 dc Khomenkova, L. author Fernández Sánchez, Paloma author Piqueras De Noriega, Francisco Javier author 2007-04 ZnO microspheres, with surfaces covered with nanowalls, as well as nano- and microrods, have been grown by thermal treatment of ZnS powder. The structures have been grown at temperatures in the range of 750-900 ºC in a catalyst-free process. Previous mechanical treatment of the ZnS powder by ball milling has been found to influence the morphology and size of the obtained structures. Cathodoluminescence in the scanning electron microscope has shown that spheres and elongated structures have an inhomogeneous luminescence emission. 1528-7483 10.1021/cg060789a https://hdl.handle.net/20.500.14352/51095 http://dx.doi.org/10.1021/cg060789a http://pubs.acs.org ZnO nanostructured microspheres and elongated structures grown by thermal treatment of ZnS powder
