Abstract:   (698 Views)
In this work, nanoparticles of ZnO with different grain sizes were synthesized by the hydrothermal method to investigate the influence of the grain size on gas-sensing performance. Sensors based on these nanoparticles were activated by UV radiation with a wavelength of 390 nm at the intensity of 0.55 mW/cm2. Sensors have been exposed to ethanol gas at low temperatures (80 °C) under UV light. The results indicate that the sensitivity is improved by reducing the grain size of the nanoparticles. It could be because the particle size of the materials synthesized was comparable to the Debye length.
