Abstract |
Zn1 – xMnxS (x = 0.00, 0.01, and 0.03) nanoparticles of size ~2 nm were synthesized using a co-precipitation method. Structural characterization by X-Ray diffraction (XRD) measurement revealed that all the synthesized samples were crystallize in the monophasic cubic zinc blende structure and monotonous decrement in the lattice constants with increasing Mn content, due to the effective Mn doping. The quantum confinement nature of nanoparticles was tested from UV-Vis absorbance measurement and the particle sizes were calculated and compared with XRD. Two emission bands observed in doped nanoparticles were attributed to defect related emission (blue) of ZnS and Mn2+ (orange) respectively, where the intensity of emission peak increases without any significant shift for increase in Mn2+ concentration. Magnetic measurements showed that all the samples exhibit antiferromagnetic with diamagnetic behavior, at room temperature.
