Peach-like ZnO microstructures are synthesized using vapor phase transport on MgO (001) substrates with a copper oxide (60nm) buffer layer.The structure and morphology of the product are investigated using an x-ray diffractometer (XRD) and a field-emission scanning electron microscope.The peaches have an average diameter of 3 μm and a wurtzite structure.To study the optical properties,photoluminescence (PL) and Raman spectroscopy are employed.A strong UV emission at 380nm in the PL spectra is observed,and a sharp and dominant peak at 437cm-1 in the Raman spectrum can be assigned to the good crystallization of obtained product.In addition,the growth mechanism of the peach-like ZnO structure is tentatively investigated based on the EDX analysis and growth time.
