Abstract
The photoluminescence intensity of the dodecanethilol-functionalized Au (DDT-Au) nanoparticle (NP) layer/4,4'-cyclohexylidenebis[N,N-bis(4-methylphenyl)benzenamine] (TAPC)/4,4'-bis(N-carbazolyl)-1,1'-biphenyl:tris(2-phenylpyridine) iridium (III) (CPB:Ir(ppy)(3)) film was increased by about 1.15 times compared to that of the TAPC/CPB:Ir(ppy)(3) film due to the effect of coupling between the excitons in the emitting layer and a localized surface plasmonic resonance (LSPR) in the DDT-Au NPs. The current efficiency of the organic light-emitting devices (OLEDs) with the DDT-Au NP layer at 100 cd/m(2) was 14.9 cd/A larger than that without the DDT-Au NP layer, resulting in an enhancement of the out-coupling efficiency. The increase in the current efficiency of the OLEDs with a DDT-Au NP layer was attributed to the enhanced out-coupling efficiency due to the existence of the LSPR generated by the DDT-Au NPs.
