The Raman Properties of Ag Doped ZnO Microrods Synthesized by Chemical Vapour Deposition
Abstract:
Ag doped ZnO microrods are prepared on c-plane sapphire substrates by chemical vapour deposition method at high temperature.The morphology, structure and optical properties were investigated by scanning electron microscopy, X-ray diffraction and Raman spectrum, respectively. The prepared Ag doped ZnO microrods have good preferred orientation with very limited structural defects. The Raman bands indicates that a tensile stress existed in the sample and an additional local vibrational mode related to Ag is also found which can be used to confirm the existence of Ag in the Ag doped ZnO microrods.
