Abstract

ZnO is multifunctional semiconductor material having useful practical applications. Zno is promising in various scientific fields like energy harvesting, sensors, nanogenerators, optoelectronics, transducers and biomedical devices due to fascinating and remarkable properties. We report growth of ZnO nanoneedles by thermal oxidation of micro particles of metallic zinc in air at 480 ºC and 500 ºC. The zinc particles are deposited on the Si substrate by dip coating method. Zinc deposited substrates are oxidized by thermal radiation method in halogen tube furnace. The whole needles are wurtzite single crystal. The growth concentration and density of nanoneedles depends on the size of metallic zinc particles, oxidation time and oxidation temperature. Scanning electron microscope (SEM).
