제목 Surface plasmon resonance of carbon dot-supported silver nanoparticles; Versatility in polymer optoelectronic devices
초록 The coupling of surface plasmons and excitons in organic materials can improve the performance of organic optoelectronic devices.1,2 Here, we fabricate solution-processed polymer light-emitting diodes (PLEDs) and polymer solar cells (PSCs) using carbon dot-supported silver nanoparticles (CD-Ag NPs). The surface plasmon resonance effect of CD-Ag NPs allows significant radiative emission and additional light absorption and achieves a remarkably enhanced current efficiency (CE) of 27.16 cd A-1 and a luminous efficiency (LE) of 18.54 lm W-1 in PLEDs as well as a power conversion efficiency (PCE) of 8.31% and an internal quantum efficiency (IQE) of 99% in PSCs compared with devices without CD-Ag NPs (CE = 11.65 cd A-1, LE = 6.33 lm W-1 in PLEDs and PCE = 7.53%, IQE = 91% in PSCs). To the best of our knowledge, these device efficiencies in PLEDs and PSCs with CD-Ag NPs are record-high values in plasmonic polymer optoelectronic devices with metal nanoparticles.
