Abstract:ZnO microwires have been synthesized by a simple chemical vapour deposition method. The morphology and optical properties were investigated by scanning electron microscopy, photoluminescence, and Raman spectrum, respectively. The strong ultraviolet emission with the weak deep-level emission observed in the photoluminescence spectrum indicates that the ZnO microwires have good optical properties with limited structural defects. In the Raman spectrum, the intense E2 modes indicate that the ZnO microwires have perfect wurtzite structure. Additionally, the red shift of the Raman peaks can be attributed to the lattice distortion and piezoelectric effect of the nanostructures. ? 2011 IEEE.
