Keywords: | NIR; energy transfer; fluorescence; organic LEDs | Issue Date: | Aug-2016 | Publisher: | WILEY-V C H VERLAG GMBH | Journal Volume: | 28 | Journal Issue: | 30 | Start page/Pages: | 6378 | Source: | Advanced materials (Deerfield Beach, Fla.) | Abstract: | Fluorescence enhancement of a high-mobility polymer semiconductor is achieved via energy transfer to a higher fluorescence quantum yield squaraine dye molecule on 50 ps timescales. In organic light-emitting diodes, an order of magnitude enhancement of the external quantum efficiency is observed without reduction in the charge-carrier mobility resulting in radiances of up to 5 W str(-1) m(-2) at 800 nm. |
