Abstract

We report on hybrid light-emitting devices based on the emission of phosphorescent sensitized colloidal CdSe/ZnS quantum dots (QDs). Emission lifetime measurements demonstrated that the energy transfer (ET) from square-planar platinum(II) complex [4-CF3-(N^C^N)PtCCC6H-4-F] (N^CH^N=1, 5-bis(2’-pyridyl)benzene) (Pt-2) to QDs is more efficient than that from octahedral iridium(III) complex bis[(4,6-difluorophenyl)pyridinato-N, C2]-(picolinato)iridium (FIrpic). This different ET efficiency might be attributed to the different spatial structures between Pt-2 and FIrpic. Pure red emission with CIE coordinates of (0.66, 0.33) and maximum external quantum efficiency of 2.08% and white emission with power efficiency of 3.15lm/W were realized at different concentrations of Pt-2 and QDs, respectively.
