“…Nevertheless, at higher frequency domain, the polarization impact was reducing. This subsequently initiated the reduction in dielectric constant at a higher frequency level [42][43][44]. Due to the incorporation of Mn dopant, the magnitude of the dielectric constant was reducing.…”

A simple, facile co-precipitation technique was successfully used to synthesize the pure, and Mn-doped SnO 2 nanoparticles (NPs) and characterized by X-ray diffraction (XRD), Fourier Transform Infrared (FT-IR)), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-vis diffuse reflectance spectroscopy and photoluminescence (PL). XRD analysis indicated that the prepared samples have the pure tetragonal structure of SnO 2. The doping of Mn on SnO 2 surface enhances the crystallite size of the SnO 2 NPs. The polycrystalline in nature SnO 2 nanoparticles was confirmed by SAED pattern. FT-IR analysis illustrates the presence of stretching vibration of the O-Sn-O bond in both SnO 2 and Mn-doped SnO 2 NPs. SEM and TEM analysis shows that the SnO 2 particles are spherical in shape and are uniformly dispersed inside the nanocomposite matrix. The average particle size of SnO 2 in pure SnO 2 and Mn-doped SnO 2 NPs was determined as~14 and 12 nm respectively. The optical analysis confirmed a redshift by doping Mn on SnO 2. The band gap energy for pure SnO 2 and Mn-doped SnO 2 NPs are 3.14 eV to 2.87 eV, respectively. The visible emission was observed from PL analysis. Photocatalytic activity of the pure SnO 2 and Mn-doped SnO 2 are tested using Rhodamine B (RhB) dye as a model compound under UV light. The results revealed that the Mn-doped SnO 2 NPs exhibited higher efficiency than pure SnO 2 for the degradation of RhB dye and furthermore with increasing the amount of Mn doping further enhanced the degradation rate of R hB dye. The synthesized samples present good reusable stability. Dielectric loss of the prepared pure and Mn-doped SnO 2 NPs exhibited a linear trend at higher frequency domain. Increased dopant amount reduced the ac conductivity which is attributed to the particle size effect with the presence of the impurities.

“…The peaks at 561 and 660 cm −1 belong to the Sn–O stretching vibration modes [ 25 , 26 ]. A weak peak at 1628 cm −1 is recognized as the deformation mode of OH groups [ 27 ]. We can also find that the increment of Y content causes a small shift to a lower wave number and the absorption peak becomes stronger.…”

Pure SnO2 and Y-doped SnO2 nanobelts 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 SnO2 nanobelt and Y-doped SnO2 nanobelt were explored to acetone, ethanol, and ethanediol. It reveals that the sensitivity of single Y-doped SnO2 nanobelt 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 SnO2 sensor and have an influence on the optical properties of Y-doped SnO2 nanobelts.Electronic supplementary materialThe online version of this article (doi:10.1186/s11671-016-1685-1) contains supplementary material, which is available to authorized users.
