Versatile surface plasmon resonance of silver nanoparticles in polymer optoelectronic devices |
| 초록 |
The coupling of surface plasmons and excitons in organic materials can improve the performance of organic optoelectronic devices. The surface plasmon resonance effect of carbon dot-supported silver nanoparticles allows significant radiative emission and additional light absorption, leading to remarkably enhanced current efficiency of 27.16 cd A-1 and a luminous efficiency of 18.54 lm W-1 in PLEDs as well as a power conversion efficiency (PCE) of 8.31% and an internal quantum efficiency of 99% in PSCs compared with control devices. Furthermore, we have demonstrated high-performance PSCs using the plasmonic effect of multi-positional silica-coated silver nanoparticles. The location of the nanoparticles is critical for increasing light absorption and scattering via enhanced electric field distribution. The device incorporating silica-coated silver nanoparticles between the hole transport layer and the active layer achieves a PCE of 8.92% with an external quantum efficiency of 81.5%. |
