ZnSxO1-x: Mn2+ (x = 0.0, 0.2, 0.4, 0.5, 0.6, 0.8 and 1.0) nanocomposites were successfully prepared by the microwave assisted solvothermal method using a domestic microwave oven. The prepared samples were annealed at 200oC for 1 hr to improve the ordering. Grain sizes and lattice parameters were determined by carrying out X-ray powder diffraction measurements. Scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDS) show the morphology and elemental analysis of the as-synthesized ZnSxO1-x: Mn2+ nanocrystals. AC and DC electrical measurements were carried out on palletised samples at various temperatures ranging from 40-150 oC. Results of the present study reveal that the space charge contribution plays a significant role in the charge transport process and polarizability in all the seven nanocrystals studied.
