Microwave irradiation of metals generates electric discharges (sparks). These sparks are used to generate metallic nanoparticle of Cu and Ni and one-dimensional nanorods of CuS, ZnF2, and NiF2 protected with fluorinated amorphous carbon. We have also synthesized reduced graphene oxide and graphene partially rolled into scrolls by this method.
