“…One-dimensional nanostructures, 3,4 owing to the restrained electron motion in confined dimensions, may exhibit novel functional properties that cannot be realised in their individual bulk counterparts, and therefore, are currently the subject of intensive research. TiO 2 nanotubes, SnO 2 nanosheets, WO 3 nanorods, ZnO nanowires and MnO 2 nanobelts [5][6][7][8][9][10][11] are just a few prototypes showing a successful outcome of low dimensional nanostructures and their potential uses in electrochemistry, optics, magnetic and gas sensing fields. Nanostructures with high aspect ratio (i.e.…”

In this study, a facile hydrothermal method was adopted to fabricate SnO 2 and CuO-SnO 2 nanoparticles. The CuO content was chosen as 5 mol.-% (sample 1), 10 mol.-% (sample 2) and 15 mol.-% (sample 3). Microstructures and surface morphologies for all samples were characterised by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HRTEM). A systematic comparison study reveals an enhanced gas sensing performance for the CuO-SnO 2 gas sensor towards CO gas. The improved gas sensing properties are attributed to the formation of p-n junctions and the absorbed oxygen species as well as to the heterojunctions of the CuO to the SnO 2 nanoparticles which provide additional reaction rooms. The results represent an advance of heterojuction nanostructures in further enhancing the functionality of gas sensors, and this simple method could be applicable to many sensing materials.

The melt‐quenching method was used to prepare two groups of samples using CdO and V2O5 as starting materials. Taking into account that a crystalline‐amorphous phase transition would be expected for the CdO–V2O5 system, a first batch was prepared varying the proportions of CdO and V2O5 in the intervals 60–95 and 40–5 wt%, respectively. With the aim of investigating the effect of erbium in the phase transition and crystalline quality of the first group of samples, a second batch was fabricated with the same proportions of CdO and V2O5, with the addition of 5 wt% of Er(NO3)5H2O as source of Er3+ ions. It was found that crystalline or amorphous samples could be obtained depending on the relative concentrations of CdO and V2O5, and that the borderline between amorphous and crystalline samples was affected by the incorporation of Er. From X‐ray diffraction, it was possible to identify the formation of the ternary compound Cd2V2O7 in the crystalline cases. The Raman and infrared bands in these samples were in agreement with the lattice modes of Cd2V2O7. Additionally, an improvement in the crystalline quality of Cd2V2O7 was obtained for the Er‐doped samples. The effect of the local environment around the Er3+ ions on the room temperature photoluminescence was also investigated for the amorphous and crystalline samples.
