Abstract

In this paper, we mainly discuss about Al-doped zinc oxide (ZnO) nanorods (NRs) grown by hydrothermal method with low temperature. Glass substrate was grown 100 nm ZnO seed layer by RF magnetron Sputter. Add zinc nitrate hexahydrate [Zn(NO3)2·6H2O] and hexamethylenetetramine (HMT, C6H12N4), and add aluminum nitrate [Al(NO3)3·9H2O] for changing conductive properties of ZnO NRs to reach the purpose of doped. Then we used field electron emission scanning electron microscope observing the surface morphology; energy dispersive spectrometer analyze element content; X-ray diffractometer; photoluminescence analyze optical properties; transmission electron microscopy view the internal type and structure of the material. Finally observing the Al-doped ZnO NRs and pure ZnO NRs sensor under methyl alcohol surroundings. The results the Al-doped ZnO NRs sensor were found to be more sensitive than the pure ZnO NRs sensor under methyl alcohol surroundings.
