Leaf‐like macroscopic ZnO nanostructures have been synthesised via a conventional thermal evaporation method at 950°C, using a mixture of graphite, zinc oxide and CuO powders as a source material. The effect of CuO in a relevant growth mechanism was discussed. Its crystal structure properties were determined using X‐ray diffraction, scanning electron microscopy and high resolution transmission electron microscopy. Photoluminescence spectra of the sample exhibit emission peaks centred at about 382, 525, 542 and 767 nm, respectively. The room temperature ferromagnetism was observed using a physical property measurement system.
