Contribution Of Fluorescence And Exciplex Emission Into Efficient White OLED

Abstract

In the paper double-channel emission from organic exciplex coupled to fluorescence emission has been shown for the first time. The process has been demonstrated for white emission in light-emitting diodes based on yellow-green organic exciplex combined with organic blue fluorescence emission. Combining the fluorescence emission of mMTDATA with the thermally activated delayed fluorescence exciplex emission from the DPNC/Bphen interface, a highly efficient white OLED has been fabricated. As a result, bright white OLED with a high luminance exceeding 10 000 cd/m2 has been obtained.
