Abstract
Achieving single phase, morphology controlled synthesis of copper sulfide (Cu2âxS) nanoparticles is quite challenging whereas, the physical and chemical properties of Cu2âxS nanoparticles rely on their crystal structure and morphology. These reasons turned the importance towards the structure and morphological controlled synthesis of Cu2âxS nanoparticles. In the present work synthesis of crystalline, single phase copper sulfide (Cu1.8S) nanodisks by a hot injection method with rhombohedral structure and controlled morphology are highlighted. Influence of the solvent on crystalline phase and morphology was analyzed. Oleic acid and 1-Octadecene were used as solvents as well as capping agents at the temperature of 180 °C. Phase and the crystallinity of the products were characterized by X-ray diffraction (XRD). Optical properties were studied by UV-vis absorption spectroscopy. Morphological analyses were carried out through SEM and TEM. Elemental composition of copper to sulfur ratio was confirmed through Energy dispersive X-ray spectroscopy (EDS). The presence of capping agent over the Cu1.8S nanodisks was confirmed from Fourier transform infrared spectroscopy (FT-IR).
