The abundant use of portable electronic devices, such as laptops, mobile phones, tablets, etc., leads to an increasing need for efficient energy-harvesting, generating, and storage systems. Therefore, developing artificial green energy resources, taking inspiration from natural processes, has been among the core areas of modern scientific research. Highly efficient organic light-emitting devices (OLEDs) promise to generate light ecologically with less electricity consumption. Thermally activated delayed fluorescence emitters (TADF) emerged as the most promising candidates for next-generation light-emitting metal-free organic materials. The current TADF OLED technology is limited by broader emission, poor device lifetime, and stability. In this project, I will engineer microcavities to fabricate highly efficient OLEDs based on a TADF host and fluorescence guest emitter system called Hyperfluorescence.
