Doping concentration dependence of microstructure and magnetic behaviours in Co-doped TiO(2) nanorods

Co-doped titanium dioxide (TiO(2)) nanorods with different doping concentrations were fabricated by a molten salt method. It is found that the morphology of TiO(2) changes from nanorods to nanoparticles with increasing doping concentration. The mechanism for the structure and phase evolution is inve...

description Co-doped titanium dioxide (TiO(2)) nanorods with different doping concentrations were fabricated by a molten salt method. It is found that the morphology of TiO(2) changes from nanorods to nanoparticles with increasing doping concentration. The mechanism for the structure and phase evolution is investigated in detail. Undoped TiO(2) nanorods show strong ferromagnetism at room temperature, whereas incorporating of Co deteriorates the ferromagnetic ordering. X-ray photoelectron spectroscopy (XPS) and electron spin resonance (ESR) results demonstrate that the ferromagnetism is associated with Ti vacancy.
