Summary:
Organic light-emitting diodes (OLEDs) already shape many everyday devices such as smartphones and high-resolution televisions. Their success comes from using self-luminous layers made of organic semiconductors, resulting in brilliant colors with low energy consumption. However, one of the last major challenges of OLED technology is creating efficient and long-lasting blue light sources. Compared to red and green emitters, blue emitters currently lag behind in stability and lifetime.
This project pursues an innovative solution: using lanthanoid complexes—specifically europium and cerium—as the foundation for new blue emitters. Although often called “rare earths,” these elements are actually widely available and provide a sustainable supply of raw materials. The molecules we develop offer high stability and are ideally suited for producing durable, efficient blue light in OLEDs.
Our development process includes several innovative steps. Using advanced computer modeling, we design new molecular structures that are then synthesized and thoroughly examined in the laboratory. These new materials are incorporated into OLED components, which are extensively tested and optimized for brightness, efficiency, and long-term stability. Supporting studies ensure the quality and practical suitability of these new blue emitters.
With this project, we aim to set new standards in OLED technology and lay the foundation for material production in Saxony. The company beeOLED will market these innovative products, broadening the circle of leading OLED manufacturers in the region. Thanks to close collaboration with the Institute of Applied Photophysics (IAPP) at TU Dresden, both the scientific community and the training of future professionals also benefit from this initiative.
