摘要：

This study reported the preparation of ZnO-coated SiOx, nanowires and investigated changes in the structural and photoluminescence (PL) characteristics resulting from application of a thermal annealing process. While X-ray diffraction (XRD) analysis revealed the annealing-induced transformation of ZnO to Zn2SiO4, transmission electron microscopy (TEM) observation suggested that shell layer tended to be transformed to nanoparticle-like structures by thermal annealing. Thermal annealing induced the changes in the shape of the PL emission spectrum. (c) 2007 Elsevier B.V. All rights reserved.
