Structural and gas sensing characteristics of ZnO nanorods grown on different substrates
ZnO nanorod arrays were grown by hydrothermal method on flat glass substrates and patterned sapphire substrates. Different growth times and concentrations of zinc acetate solution were performed for ZnO nanorod growth to investigate the structural and CO gas sensing properties. The highest gas sensing response was obtained with the growth time of 60 min and zinc acetate concentration of 0.03 M for both types of substrates. The sensing responses under different temperature and gas concentration were also measured. The highest responses was 1.85 and 1.75 for the flat glass substrates and the patterned sapphire substrates, respectively, under the temperature of 300 °C and the CO gas concentration of 2000 ppm. The response times of 200 and 110 s were achieved for the flat glass substrates and the patterned sapphire substrates, respectively.
