Kaur, S. Bhattacharya, M. Roy, S.K. Deshpande, P. Sharma, S.K. Gupta, J.V. Yakhmi] ZnO micro- and nanostructures were prepared by thermal evaporation of Zn and a mixture of ZnO with graphite. On heating Zn powder in a quartz tube at temperatures between 600°C to 800°C, radial growth of nanowires was observed on the source. On increasing the temperature to 900°C, various interesting micro- and nanostructures of Zn and ZnO were observed to have deposited all over the quartz tube. On the other hand, when ZnO was heated in the presence of graphite, predominant growth of ZnO nanotetrapods was observed. Nanowires and tetrapods of ZnO were characterized by photoluminescence measurements and were found to show significantly improved response for detection of H2S gas at room temperature when compared with earlier studies. The response was seen to improve with increase in oxygen vacancies in the material. Springer-Verlag, 2007 Kaur M.
