Abstract:
In this work, we reported the energy transfer between Mn doped CdS quantum dots (Mn:CdS QDs) with the core–shell structure of MnS/ZnS/CdS and 1,3,5-tris( N -phenylbenz-imidazol-2,yl) benzene (TPBI) in inorganic/organic blend films by steady-state and time-resolved photoluminescence (PL) spectroscopy. The changes in PL excitation intensity of the Mn:CdS QDs and PL lifetime of the TPBI clearly demonstrate an efficient energy transfer process from TPBI to QDs in the blend films. Further, it is found that the efficiency of Förster resonance energy transfer increases with the increasing of the thicknesses of CdS shell. These results highlight the potential of Mn doped QDs for fabricating high-performance QD light-emitting diodes.
