In this work, we explore the effects of the ultrastrong coupling regime between light and molecular exci-tons on the electrical and optical properties of microcavity-OLEDs. We studied two different sampleshaving a coupling value of 31% and 48%. The main effect of the ultrastrong interaction is on the electro-luminescent emission linewidth which was only 28 meV, that is about 12-fold narrower than that of thecorresponding photoluminescence of the uncoupled material and even half the linewidth of photonic(weak-coupled) microcavity working at the same wavelength.

Abstract
In this work, we explore the effects of the ultrastrong coupling regime between light and molecular exci-tons on the electrical and optical properties of microcavity-OLEDs. We studied two different sampleshaving a coupling value of 31% and 48%. The main effect of the ultrastrong interaction is on the electro-luminescent emission linewidth which was only 28 meV, that is about 12-fold narrower than that of thecorresponding photoluminescence of the uncoupled material and even half the linewidth of photonic(weak-coupled) microcavity working at the same wavelength.File in questo prodotto:
