“…SnO 2 is a material that can be easily doped with a variety of impurities, and it was shown that the properties of SnO 2 nanostructures can be handled by doping it with adequate impurities. , SnO 2 nanoparticles have been successfully doped with transition-metal ions (V, Fe, Co, Mn, and Cu). − In particular, V-doping is expected to have significant effect on optical response ,, of SnO 2 (the name “vanadium” is originated in the mythological Scandinavian god Vanadis because of its multicolored compounds), its electronic and catalytic properties, , and it can induce a ferromagnetic response at high temperature. ,,, …”
