Abstract
In the present study, the use of ZnO nanorods sensor under the irradiation of 400 nm UV-LED illumination at room temperature was tested. The non-intentionally C-doped flower-like zinc oxide (ZnO) nanorods were synthesized through a chemical method at low temperature (60–65 °C). The hexagonal wurtzite phase of ZnO was confirmed by X-ray diffraction (XRD). The samples were too characterized using SEM, EDX, TEM, XPS, BET and UV-Vis spectroscopy. The results show that the ZnO nanorods behave as a p-type sensor with a high response and reversibility towards ethanol and ammonia and it is an attractive chemical sensing material.

Keywords
