Special lath-like ZnO crystals and arrays of well-aligned ZnO nano/micro-composite rods were synthesized on ZnO seed-coated glass substrates by aqueous chemical growth (ACG) method. PEG was added into the seed precursor solution to obtain seed layers with different textures, on which nano/micro-composite rods were formed. Special lath-like crystals were fabricated by prolonging the growth time to 48 h. X-ray diffraction and scanning electron microscopy analyses reveal that highly c-oriented rod crystals grow vertically from the substrate. The possible growth mechanism concerning special lath-like crystals and nano/micro-composite rods has been discussed.
