Magnetooptical studies of CdSe/(Zn,Mn)Se semimagnetic nanostructures

• In conclusion the performed magneto-PL measurements exhibit fonrmation of 0D excitons in CdSe/(Zn,Mn)Se nanostructures. The excitonic states forming the inhomogeneously broadened emission band differ both in their energy (due to fluctuations in the sizes and compositions among the localization sites) and in magnetic properties (most probably, due to the effect of Mn ions clustering in the nearby regions). The structure potential for spin-related optoelectronic applications is demonstrated, owing to almost complete circular polarization of the emitted light within the wide spectral range (about 1OO meV) at moderate magnetic fields.
