Exciton management in organic light-emitting diodes (OLEDs) is vital for improving efficiency, reducing device aging, and creating new device architectures. In particular in white OLEDs, exothermic Förster-type exciton transfer, e.g. from blue to re

In this study we demonstrate how a mechanistic description can be obtained of the interplay of all processes that give rise to the efficiency loss due to triplet polaron quenching (TPQ) in phosphorescent host-guest systems such as used in organic lig

The efficiency of organic light-emitting diodes that utilize the principle of thermally activated delayed fluorescence (TADF) depends sensitively on the host material in which the TADF emitter molecules (guests) are embedded. Potential loss processes

For thermally activated delayed fluorescence (TADF) host-guest systems used in organic light-emitting diodes, understanding of the transient photoluminescence (PL) measurements is crucial for accurate determination of the photophysical rates of the e

The functioning of organic optoelectronic devices such as organic light-emitting diodes (OLEDs) is determined in part by the dielectric permittivity ϵ of the organic materials used, at frequencies that vary from quasistatic to the optical range. The

Minimizing the reverse bias dark current while retaining external quantum efficiency is crucial if the light detection sensitivity of organic photodiodes (OPDs) is to compete with inorganic photodetectors. However, a quantitative relationship between

We present an ab initio computational study of triplet exciton diffusion in four phosphorescent emitters commonly used in organic light-emitting diodes (OLEDs). By kinetic Monte Carlo simulations, triplet diffusion lengths are obtained for these emit
