Abstract：In this study, rose-like nickel oxide (NiO) nanoparticles with diameters of 400–500 nm are prepared on ITO glass substrates by simple electrodeposition in NiSO46H2O solution at room temperature followed by oxidation in air. Scanning electron microscopy, x-ray diffraction and a transmission electron microscope are used for analyses of the NiO nanoparticles. The ethanol gas sensitivity of these nanoparticles is studied. The results indicate that the rose-like NiO nanoparticles could be used for the fabrication of ethanol gas sensors to monitor the low concentration of ethanol gas in air. Furthermore, at 5 ppm, the NiO nanorose-based sensors show a high response to ethanol (Rg/Ra=8.4).
