“…The compounds like MgSnO 3 , CaSnO 3 , SrSnO 3 and BaSnO 3 belongs to this category and have been extensively investigated for their optical properties [4][5][6][7]. For many of the alkaline earth stannates, alkaline earth tin hydroxides having general formula MSn(OH) 6 are used as the precursor materials.…”

“…[1][2][3] Compounds like MgSnO 3 , CaSnO 3 , SrSnO 3 and BaSnO 3 belongs to this category and have been extensively investigated for their optical properties. [4][5][6][7] Doping lanthanide ions into such lattices is an attractive option to make efficient luminescent materials based on MSnO 3 for different optical applications, including multicolour solid state light emitters. Among the different MSnO 3 nanomaterials doped with lanthanide ions, CaSnO 3 :Ln and SrSnO 3 :Ln have improved luminescent properties compared to BaSnO 3 :Ln nanoparticles.…”

The present study describes the structural and luminescent properties of SrSnO(3) nanorods containing Eu(3+) ions. Based on Rietveld refinement of XRD patterns corresponding to both undoped and europium doped SrSnO(3) nanorods, it is inferred that the average bond lengths of Sr-O1 linkages, which have a square planar geometry around Sr(2+) in the SrO(12) polyhedra present in SrSnO(3), remained unaffected with Eu(3+) incorporation into the lattice. However, the average bond lengths of shorter Sr-O2 linkages increase and longer Sr-O2 linkages decrease with Eu(3+) doping into the SrSnO(3) lattice. A lack of variation in the lattice parameters of SrSnO(3) with doped Eu(3+) ions is explained based on mutually compensating changes in the average bond lengths of the Sr-O2 linkages in the unit cell. Luminescence studies have confirmed that Eu(3+) ions occupy the centrosymmetric Sr(2+) site only up to 2 at%, beyond which Eu(3+) ions exist in a significantly distorted environment (grain boundaries). Beyond 3%, incorporation of Eu(3+) ions into the SrSnO(3) lattice leads to the formation of a Eu(2)Sn(2)O(7) phase. From the EPR studies it is confirmed that around 5% of the incorporated Eu(3+) ions get converted to Eu(2+) ions and they occupy Sr(2+) sites in the lattice.

“…5. The arc at high frequencies is attributed to the bulk contribution and the straight sloping line at the low‐frequency region is related to the process of diffusion between the electrode and electrolyte [27]. The TiO 2 /SiO 2 –ATO composite exhibits a comparatively small semicircle compared with the TiO 2 /ATO composite, indicating the lower resistance for the TiO 2 /SiO 2 –ATO composite [25, 28].…”

The effect of the TiO 2 surface property on the conductivity of TiO 2 /antimony-doped tin oxide (ATO) has been revealed by the substrate modification with SiO 2 and ZrO 2. Their morphology, structural, and electric characteristics were investigated through field emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and electrochemical impedance spectra. The surface character of the raw and modified TiO 2 particles in water was investigated. The results indicated that the negatively charged substrate (−29.7 mV) was formed through the incorporation of SiO 2 coating, which facilitated the uniform deposition of positively charged ATO precursors further significantly improved the conductivity of TiO 2 /ATO composite. Conversely, the conductivity of TiO 2 /ZrO 2-ATO composite decreased due to the increase of electrostatic repulsion from the positively charged surface (+55.3 mV) of the substrate. The results confirmed the feasibility of the method proposed in this work.
