Fabrication, characterization and magnetic properties of Mn-doped SnO nanostructures via hydrothermal method

In the present study we report synthesis of Mn-doped SnO nano sheets and nano cubes via facile hydrothermal technique with controlled morphology. X-ray diffraction, field-emission scanning electron microscopy, energy dispersive X-ray spectroscopy and alternating gradient magnetometer techniques were used to investigate the physiochemical characterizations. Field-emission scanning electron microscopy results exhibited the rectangular shape of the sheets with diagonal length of 1-2 µm which were found in the form of bundles, the average size of nano-hexagonal plate and the average size of the quadrilateral face of three dimensional nano-cube were about 100 nm. Experimental results confirmed that the different chemical bases exhibit a strong influence on morphology of the resulting product and doping concentration had effect on the size of nano-cubes. Furthermore, room temperature ferromagnetism increases monotonically for Mn doping and reaches maximum saturation magnetization emu/g for 3% Mn-doped SnO.
