Synthesis and optical characterization of monodispersed Mn2+ doped CdS nanoparticles

Monodispersed Mn2+ doped CdS nanoparticles with average size as small as 1.8 nm have been synthesized through chemical method. The nanostructures of the prepared nanoparticles have been confirmed through X-ray diffraction (XRD), ultraviolet-visible (UV-vis) absorption and transmission electron microscope (TEM) measurements. The photoluminescence emission covering 450–650 nm of the visible region is observed under ultraviolet light excitation, from Mn2+ doped CdS nanoparticles dispersed in dimethyl sulfoxide (DMSO).
