Enhancement and Quenching of Fluorescence by Silver Nanoparticles in Organic Light-Emitting Diodes

Abstract EN

The influence of silver nanoparticles (SNPs) on the performance of organic light-emitting diodes (OLEDs) is investigated in this study.

The SNPs are introduced between the electron-transport layers by means of thermal evaporation.

SNPs are found to have the surface plasmon resonance at wavelength 525 nm when the mean particle size of SNPs is 34 nm.

The optimized OLED, in terms of the spacing between the emitting layer and SNPs, is found to have the maximum luminance 2.4 times higher than that in the OLED without SNPs.

The energy transfer between exciton and surface plasmons with the different spacing distances has been studied.
