ZnO nanotetrapods were synthesized by a simple thermal evaporation of Zn powder at a relatively low temperature ∼600 °C. The tetrapods have four legs with hexagonal cross-section. Interpenetrating growth was observed in some of these nanotetrapods. Multipod ZnO nanoforms were produced at higher temperature. The optical characterizations such as optical absorbance, photoluminescence and Raman spectroscopy reveal excellent crystal qualities of these nanoforms. The field emission studies indicated that these nanoforms could be utilized in field emission based devices.

Sensitized Solar Cells

Antimony doped ZnO (ZnO:Sb) fiber was grown by a simple thermal evaporation process of Zn powder and Sb2O3 . Scanning Electron Microscopy (SEM) shows that the grown fiber reaches more than 70 μm, which is the longest ZnO fiber reported in literature. Electron Backscattered Diffraction (EBSD) study indicates that this crystal is composed of three main phases: antimony doped zinc oxide (ZnO:Sb) , ordonezite (ZnSb2O6) and zinc antimony oxide (Zn7Sb2O12) . The current–voltage (I–V) characteristics demonstrate that the conversion efficiency of dye sensitized solar cell was greatly enhanced by ZnO:Sb fiber.
