The scientific goal of this project is to obtain a better understanding of photophysical processes in organic light-emitting diodes (OLEDs) in order to enable further progress in that field. In particular, we are interested in understanding their impact on efficiency and lifetime and the transfer of these achievements to application. This requires the development of dedicated measurement and analysis tools, including numerical simulation, together with suitable processing conditions and taylor-made materials for tuning the photophysical properties of emitter systems and their implementation in OLEDs. We are aiming at both harvesting the potential for efficency improvement of OLEDs in the pristine state as well as reducing photophysical aging processes.

该项目的科学目标是更好地了解有机发光二极管(OLED)的光物理过程，以便在该领域取得进一步进展。特别是，我们有兴趣了解它们对效率和寿命的影响以及将这些成果转化为应用。这需要开发专用的测量和分析工具，包括数值模拟，以及适当的工艺条件和泰勒制造的材料，以调整发射器系统的光物理特性及其在有机发光二极管中的实现。我们的目标既是挖掘OLED在原始状态下提高效率的潜力，也是为了减少光物理老化过程。
