Paper Abstract

Spectroscopy of individual CdSe Quantum Dots embedded in an innovative type Zn1-xCdxSe (xCd of up to 0.3) barrier of lower energy than a typical ZnSe one, is reported. A polarization transfer efficiency of up to -26.1% for the Quantum Dot without a Mn2+ ion and optical addressing of the QD embedding a single Mn2+ ion using a quasi-resonant excitation is demonstrated. Thanks to a shifting of QD emission energy below Mn2+ intraionic transition, operation of the studied QDs doped with several Mn2+ ions should be feasible without a loss of the QD quantum yield. This is beneficial for implementation of the presented Quantum Dots in magnetooptical devices operating in the visible spectral range.
