Growth and characterization of zinc oxide nanostructures by local heating method

Abstract

In the present work 1D Zinc Oxide nanostructures were synthesized sucesfuly by local heating method at various concentration and temperature. Crystaline nature of ZnO
nanostructures was confirmed by the apearance of high intensity peak at (0 0 2) in X-ray difraction analysis of diferent samples. FESEM analysis confirmed the formation of long 1D ZnO nanostructures of about 4.5µm in length.The efective synthesis of ZnO nanostructures from the oxidation of Zn was also confirmed by FTIR analyses.The UV detection characteristics of the ZnO/Si nanostructures were studied by measuring curent- voltage I-V relationships with and without UV-B light (310-370) nm. UV detection was studied and shows the time evolution of curent of the nanorods under UV ilumination for surface with modification by coating Poly Styrene Sulfonate (PS).
