Abstract. The microspheres of stannous oxide were synthesized via simple room temperature wet chemical route using potassium hydroxide (KOH) as the precipitating agent. The prepared samples were characterized by the X-ray diffractometry (XRD), Scanning electron microscopy (SEM), and Photoluminescence and Ultraviolet-visible spectroscopy. The structural, optical and morphological properties of synthesized samples were controlled by varying the concentration of precipitating agent. It was observed that, the concentration of KOH affected the sample morphology and phase also. XRD study showed the change in phase from stannic oxide (SnO2) to stannous oxide (SnO), with increase in KOH concentration. SEM micrograph showed the change in morphology from nanoparticle network to the porous microsphere as an effect of variation of KOH concentration. TEM confirm the formation of flower like morphology by interconnection of nanosheets having < 200 nm in size. In this study, the size of individual SnO microsphere was controlled in the range of 10–14 μm in diameter, suitable for various photocatalytic and sensing applications.
