Abstract: There is provided a method for manufacturing a plurality of nanostructures comprising the steps of providing a plurality of spherical Zn structures and oxidizing the spherical structures in ambient atmosphere at a temperature in the range of 350° C. to 600° C. for a time period in the range of h to 172 h, such that ZnO nanowires protruding from the spherical structures are formed. There is also provided a field emission arrangement comprising a cathode having the aforementioned ZnO nanowire structures arranged thereon.
