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 …
