Variation of structural, optical and magnetic properties with Co-doping in Sn1−xCoxO2 nanoparticles

Effects of structural, optical and ferromagnetic states on the photocatalytic activities of Sn–TiO2 nanocrystals

“…This extension of ferromagnetic interaction should also be the reason of enhanced M s in Sn-Ti-x samples. The pristine SnO 2 sample reported the diamagnetic behavior 64,65 with the very weak ferromagnetic signal resulting possibly from native defects, 66,67 while the Sn-Ti-x (x ¼ 0.17, 0.30, 1.14 and 1.37) displays the mixture of diamagnetic and ferromagnetic behaviors as shown in Fig. 12b.…”

Enhanced Photocatalytic Activity of Vanadium-Doped SnO2 Nanoparticles in Rhodamine B Degradation

“…So far, several attempts have been conducted on doping SnO 2 NPs with transition metals such as cobalt [37,38], nickel [39], chromium [40], iron [41], magnesium [42], and vanadium [43], aiming to extend the photo response of SnO 2 from the ultraviolet to the visible region [44]. Moreover, adding amounts of these dopant species can efficiently extend the absorption edge of SnO 2 NPs into the visible region which increases the photocatalytic activity.…”

Structural, optical and magnetic properties of (In0.90Sn0.05Cu0.05)2O3 nanoparticles

“…The hysteresis loop shows a high coercive field (Hc) of 683 G. The observed magnetic moment is almost equal to that of magnetic moment observed by Peleckis et al [8] Whereas the strength of magnetization decreased in Cu doped ITO nanoparticles. The observed saturation magnetic moments are better than that of saturation magnetic moment of Co doped SnO 2 nanoparticles prepared by co-precipitation method [9]. Fig .5 shows the M-H curve of ITO nanoparticles at 100 K. From the figure it is clear that the saturation magnetic moment decreased at lower temperature.…”
