Effect of Deposition Rates on the Morphology and Efficiency of Blue TADF OLEDs — •Tolga Durmus, Marius Schnapp, Ahmed Mohamed, Vladimir Dyakonov, and Andreas Sperlich — Experimental Physics 6, University of Würzburg, 97074 Würzburg, Germany

The efficiency and stability of blue thermally activated delayed fluorescence (TADF) OLEDs are strongly influenced by the structural properties of their active layers. In this study, we investigate the impact of varying deposition rates on the morphology of these layers, focusing on their amorphous or crystalline nature. Atomic force microscopy (AFM) is used to analyze the surface morphology of the deposited layers and we aim to establish a correlation between the deposition conditions, the structural properties of the layers, and the efficiency of the OLEDs. These investigations are expected to provide valuable insights into optimizing fabrication parameters for improved blue TADF-OLEDs.
