Figure 5

Gas sensitivities of CuO nanoplatelet based sensors as a function of the gas concentrations of (a) acetone, (b) butanol, (c) ethanol and (d) isopropanol gases.

For comparison, the gas sensing performances of CuO nanoparticles are also presented. The insets are the corresponding real-time gas-sensing curves for the CuO nanoplatelets (red) and nanoparticles (black), with the concentrations of the test gas in ppm given above the peaks.
