Abstract
- In this paper, we have reported undoped and Co doped CuS nanorods by using co-precipitation method. Dehydrated Copper Chloride and Thiourea were used as main precursors and NaOH as a complexing agent in this synthesis process. The reaction takes place at room temperature. The powder samples were obtained under 100 °C using an oven for 3 h and analyzed by using various techniques like X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and UV–Vis spectroscopy. X-ray diffraction spectra exhibit the poly crystalline behavior with hexagonal phase. FESEM micrographs exhibit the randomly oriented few micrometer long CuS nanorods in vertical directions with diameter 10–15 nm. With the addition of cobalt, the nanorod converts into nanosheets with average length 2 µm and diameter 80 nm. Optical studies show the optical band gap of about 1.09–1.19 nm which is good for optoelectronic devices.
