title: Multipod znO nanoforms: low temperature synthesis and characterization.
abstract: ZnO nanotetrapods were synthesized by a simple thermal evaporation of Zn powder at a relatively low temperature approximately 600 degrees 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.
