The films were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM) and UV–vis spectroscopy. From XRD and TEM observations it was concluded that the In2S3 nanorods and microrods have ∼50nm and ∼0.5μm diameter, respectively. A plausible

Growth of dendritic flower and stoichiometry of copper sulphide depended upon reaction time at a constant temperature.
