This interdisciplinary project will study fundamental issues related to OLEDs (organic light-emitting diodes) to propose technological improvements to hyper fluorescence-based near-infrared OLEDs through forming a tripartite cooperative team from Latvia (Riga Technical University, RTU), Lithuania (Kaunas University of Technology, KTU), and Taiwan (Yuan Ze University, YZU). This project will focus on developing near-infrared OLEDs with a delicate device architecture that can generate spectra with emission peaks exceeding 900 nm. The RTU group will design and synthesize specific metalloorganic thermally activated delayed fluorescence (TADF) emitters with either direct near-infrared emission or sensitizing functionality for hyper fluorescence OLEDs in conjunction with newly-developed appropriate fluorescent near-infrared emitters. The KTU group will develop and synthesize host materials and charge transporting materials with high and balanced carrier mobility. The YZU group will develop exciplex host systems and highly out-coupling metal-alloy electrodes. This project aim is to design hyper fluorescence -based near-infrared OLEDs using the synthesized materials to achieve target spectral profiles and long device lifetimes.

Project results:
There is a significant global need for new materials with either improved or novel properties for use in various innovative applications for advanced technologies. In particular, TADF emitters and corresponding light-emitting devices represent a significant current challenge in the chemical and material sciences and in electronic engineering. Furthermore, devices with near-infrared emissions play an essential role in technological applications for 3D sensing. Therefore, the proposed research topic and the challenges that it intends to address are currently of fast-growing global interest. The results obtained from the project are expected to yield a series of publications in high-impact journals in the chemical and material sciences. Presenting these results at a prestigious national and international conferences in molecular chemistry, photochemistry, and optoelectronics will ensure wide dissemination of the results.
