Abstract

Manganese doped cadmium sulfide (CdS:Mn) nanoparticles with varying weight percentage 2, and 10 % have been synthesized by wet chemical reaction route under argon atmosphere using mercaptoethanol as a capping agent. The obtained nanoparticles are characterized by X-ray diffraction, energy dispersive X-ray (EDX) and vibrating sample magnetometer (VSM) technique. The crystal size estimated from (XRD) of the prepared NPs was about 4 - 6 nm with cubic zinc blende structure. VSM data of Mn doped CdS nanoparticles show weak hysteresis loops at room temperature indicating the superparamagnetic behavior that can be change to ferromagnetic by cooling the samples to 20 0 K.
