We demonstrate the solution-processable polymer LEDs (PLEDs) and polymer SCs (PSCs) using carbon dot-supported silver nanoparticles (CD-Ag NPs). Collective surface plasmon ensemble of CD-Ag NPs allows the coupling of individual surface plasmon to the noticeable enhancement of device performance; thereby achieving a remarkably enhanced current efficiency (CE) of 27.16 cd/A and luminous efficiency (LE) of 18.54 lm/W in PLED, and power conversion efficiency (PCE) of 8.08% in PSC, compared to those of the devices without CD-Ag NPs (CE = 11.65 cd/A and LE = 6.33 lm/W in PLED, and PCE = 7.32% in PSC). To our knowledge, this LE in PLED with CD-Ag NPs is one of the highest values in fluorescent PLEDs based on solution process. |
