Abstract
2 % Cr doped ZnS nanoparticles were synthesized using chemical co-precipitation technique. Powder X-ray diffraction reveals that Cr incorporates into the ZnS crystal lattice without troubling the original cubic structure. Transmission electron microscopy measurements show that the average size of these nanoparticles is in the range 3–4 nm. Room temperature photoluminescence studies show the increase in defects with increase in nitrogen co-doping. 2 % Cr doped ZnS exhibit hysteresis loop at room temperature indicating the magnetic behavior with diamagnetic contribution with increase in applied field. Increase in nitrogen co-doping along with Cr in ZnS shows enhanced ferromagnetism with saturated magnetization.
