Abstract :
In this study, nanocomposites of CuSxO(1-x) (with x values 0.0, 0.2, 0.4, 0.5, 0.6, 0.8, 1.0) was prepared by simple microwave assisted solvothermal method using distilled water as solvent. The as-prepared samples are annealed at 200 °C. They were characterized using powder X-ray diffraction analysis (PXRD) and vibrating sample magnetometer (VSM) measurements. The PXRD results demonstrate that the end members of CuSxO(1-x) nanocomposites (for x = 1.0 and 0.0) has hexagonal structure of CuS and monoclinic structure of CuO respectively. The middle composition of CuSxO(1-x) nanocomposites (for x = 0.8, 0.6, 0.5, 0.4, 0.2) has mixed phase of hexagonal and monoclinic structures, which confirms the formation of CuSxO(1-x) nanocomposites. The average crystallite size was calculated from Scherrer equation. The VSM measurements of all the proposed samples indicate the paramagnetic nature. The results obtained were reported and discussed herewith.
