The technique of colloidal chemistry has been applied for synthesis of nonmagnetic CdS and Cd1−xMnxS semimagnetic semiconductor nanocrystals. The Cd1−xMnxS nanocrystals have been synthesized by means of substitution reaction. The performed TEM analysis suggests of spherical shape of nanoparticles for the colloidal Cd1−xMnxS nanoparticles. The optical properties of the obtained nanocomposite solution have been investigated by absorption and emission spectroscopy. Optical spectra demonstrate features which are associated with confinement effect and change of Mn content x in the Cd1−xMnxS nanocrystals. Compositional information have been obtained on the base of the model of weak confinement regime and estimation the energy gap for a given composition of the II1−xMnxVI alloys at room temperature.
