We present a novel colloidal route to photoluminescent CdS quantum dots and the doping of these nanoparticles with divalent manganese ions, resulting in emission caused by Mn2+ in addition to the band gap related emission of CdS. The semimagnetic semiconductor was synthesized using dithiol 1,2-bis(mercaptomethyl)benzene as stabilizer. The purified and redispersed powder was characterized by UV/VIS absorption, photoluminescence, Raman, SQUID, and EPR spectroscopy.
