CdSe colloidal nanocrystals (∼3.7 nm) with zinc blende structure were synthesized at a low temperature via an inverse micelle technique. They were successfully doped with ∼4 at. % Mn, which was examined using inductively coupled plasma atomic emission spectroscopy. In spite of larger particle size (∼4.1 nm), the Mn-doped CdSe nanocrystals showed an apparent blueshift in the UV-visible spectroscopy light absorption peaks. Considering the nanoparticle size and the effective energy band gap, the increase in the bulk energy band gap was estimated in the Mn-doped CdSe nanocrystals, which provides an obvious evidence of true Mn doping in the CdSe lattices.
