Effect of Mn doping on the structural, magnetic, optical and electrical properties of ZrO2–SnO2 thin films prepared by sol–gel method

Oxygen vacancies generated by Sn-doped ZrO2 promoting the synthesis of dimethyl carbonate from methanol and CO2

“…However, according to our research, in Zr 1 /Sn and Zr 1.5 /Sn, 2q ¼ 31.5 , 51.2 show the (002) and ( 103) crystal plane growth of orthogonal ZrSnO 4 [PDF 48-0889]. 26 The formation of ZrSnO 4 is due to the solubility of Sn 4+ ions in the ZrO 2 lattice obtained upon crystallization. However, it is not ruled out that other Zr n / Sn samples also contain a small amount of ZrSnO 4 .…”

“…In order to prove that the introduction of Zr defect states in the band gap region will cause the change of disorder, we introduce a concept 1/ D . 26 1/ D represents the average crystallite size, which is determined by the ratio of the surface area to the volume of the constituent particles of the sample. As the grain size decreases, more and more disorder is introduced into the sample.…”

“…58,59 According to the results obtained in this work and previous reports, tin doping into the zirconia lattice will increase the number of active oxygen vacancies on the surface of zirconia, thereby promoting the interaction between Zr n /Sn and carbon dioxide. 25,26,39 3.11. In situ FTIR study Fig.…”

Investigation of Magnetic and Optical Properties of Mn-Doped SnO₂ at Different Annealing Temperatures

“…Ahmed et al [13] studied that varying concentration of TM doping can alter the room temperature electrical and dielectric properties. In similar manner, it has been observed by many research groups that room temperature ferromagnetism, structural and optical properties of SnO 2 can be tuned by doping it with transition metals [14][15][16][17][18][19][20]. Optoelectronic properties like band gap and photoluminescence can also be tuned by impurity doping in SnO 2 [21] .…”

Size and Magnetic Effect of Manganese (Mn) Doped Zirconia (Zro2) Nanoparticles

“…Comparison of XRD and magnetic studies were presented in Table-I. Therefore, transition metal ion Mn 2+ influences the magnetic properties of ZrO 2 nanoparticle, and hence, it is a capable material for spintronic devices [24,25]. Moreover, dopant and dopant concentrations, defect levels in the materials are the responsible for the ferromagnetism of the synthesized samples.…”
