Pure and manganese (Mn)-doped cadmium sulfide (CdS) nanoparticles with varying Mn wt% of 2, 4, 6, 8, and 10% have been synthesized by wet chemical reaction route using mercaptoethanol as a capping agent. The synthesized nanoparticles are characterized by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FTIR), photoluminescence (PL) spectroscopy, and vibrating sample magnetometer (VSM) techniques. XRD analysis shows that the as-prepared samples have crystallite size in the range of 4–7 nm with cubic zinc blende structure and transforms to hexagonal wurtzite structure by thermal annealing at 300 °C for 1 h. EDX and FTIR spectroscopy have confirmed the incorporation of Mn in the CdS lattice. Magnetic hysteresis loops were observed at low temperatures inferring the enhanced surface effects of the small-sized Mn-doped CdS nanoparticles.
