Organic light-emitting devices are now widely used in consumer electronics displays, where they enable lighter and thinner devices using less energy than conventional LEDs. Thermally-activated delayed fluorescence (TADF) molecules are novel emitters showing, among many advantages, potentially 100% efficiency and avoidance of shortages of ordinary fluorescent/phosphorescent compounds. The efficiency of the light emission process depends on the relative energy of the materials excited states. TADF-FIELD plans to address the following key research question: “can an horizontal (external) electric field improve light emission process in these materials?”. To achieve this, we plan to test these materials in a field-effect-based organic light-emitting device platform (i.e. OLETs), so far largely unexplored. Project will be carried by the Organic Electronics group at the Department of Electronics & Nanoengineering, School of Electrical Engineering at Aalto University (Espoo).
