摘要：

Stimulated emission (SE) T-4(1) -> (6)A(1) bands of Mn2+(3d(5)) in ZnxCd1-xS or ZnxCd1-xS/ZnS quantum dots were detected in the femtosecond transient absorption spectra at a time delay of 120 fs. Multiexponential rise of SE(Mn2+) amplitude due to nonradiative energy transfer to Mn2+(3d(5)) occurs both in the femtosecond and picosecond time domain. Transient kinetics of SE(Mn2+) band reveals the dynamics of energy transfer to Mn2+ (3d(5)) with time constants tau(1) similar to 400-600 fs, tau(2) similar to 4-6 ps and tau(3) similar to 87-112 ps. A possible mechanism of ultrafast energy transfer to the Mn2+(3d(5)) center accompanied by spin-flip is discussed.
