title: The Sensing Properties of Single Y-Doped SnO2Nanobelt Device to Acetone.
abstract: Pure SnO2and Y-doped SnO2nanobelts were prepared by thermal evaporation at 1350 °C in the presence of Ar carrier gas (30 sccm). The samples were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), energy dispersion spectrometer (EDS), X-ray photoelectron spectrometer (XPS), UV-Vis absorption spectroscopy, Raman spectroscopy, and Fourier transform infrared spectrum (FTIR). The sensing properties of the devices based on a single SnO2nanobelt and Y-doped SnO2nanobelt were explored to acetone, ethanol, and ethanediol. It reveals that the sensitivity of single Y-doped SnO2nanobelt device is 11.4 to 100 ppm of acetone at 210 °C, which is the highest response among the three tested VOC gases. Y3+ions improve the sensitivity of SnO2sensor and have an influence on the optical properties of Y-doped SnO2nanobelts.
