Abstract
In this study, a unique Zinc Oxide (ZnO) nanorod was isolated and subsequently heat treated at different temperatures. ZnO nanorods were synthesized by vapor transport method. Scanning electron microscope (SEM) micrographs of a unique nanorod after periodic heat treatments, gave direct evidence of a systematic degradation. X-Ray diffraction (XRD) results suggest that crystal quality improved by annealing. Optical properties can be tuned by carefully adjusting the annealing conditions. Single nanostructure based UV sensor was fabricated and the results clearly suggested a potential for using ZnO as sensitive single particle sensor for UV light.
