Transition metal cobalt‐doped zinc oxide (ZnO) nanorods with room‐temperature ferromagnetism have been rationally fabricated by a facile solution‐based route. The synthesis just involves hydrolyses and condensation processes, which allow the growth of transition metal‐doped ZnO nanostructures at a high yield, low cost, and mild temperatures. The morphology of the products can be controlled by tuning the reaction conditions such as precursors, solvents, and reaction time. The nanorods show room‐temperature ferromagnetic behavior using C 20 H 37 NaO 7 S as a surfactant. The origin of the ferromagnetism is also discussed.
