In this paper, the researchers analyze the influence of organic HTL on the QLED dynamics and mobilities in HTL and correlate this with the dynamics of the QLED (-> determined by Modulated Electroluminescence Spectroscopy (MELS)). The researchers used the characterization tool Paios. In particular, the phase shift from MELS was used as a figure of merit for the QLED dynamics.
