The electroluminescence intensity of the phenanthrene‐functionalized gold nanoparticles, PMPT‐Au nanoparticles/CPB: Ir(PIA) 2 (acac) film, was increased by 4.9 times compared with control device, CPB: Ir(PIA) 2 (acac) due to coupling between the excitons of emissive layer and localized surface plasmonic resonance of PMPT‐Au NPs. The maximum luminous efficiencies of devices II to IV with PMPT‐Au NPs were 39.2 cd A −1 (11.8 V), 40.1 cd A −1 (10.5 V), and 43.1 cd A −1 (9.0 V), respectively. The increment of current efficiency with PMPT‐Au NP coated devices was strongly related to the energy transfer between the radiated light generated from CBP: Ir(PIA) 2 (acac) emissive layer and localized surface plasmonic resonance excited by PMPT‐Au NP layer.
