Multiple-resonance (MR) thermally activated delayed fluorescence (TADF) materials are the current research hotspot in organic light-emitting diodes (OLEDs) due to their ability to deliver remarkable color purity with full-width-at-half maximum (FWHM 600 nm) MR-TADF emitters i.e. pure-red/NIR MR-TADF emitters without compromising the emission color purity (FWHM < 25 nm) and efficiency roll-off of OLEDs. These materials are not only applicable in OLEDs, but also useful in night vision displays, sensors and information-secured displays. To this end, here we proposed two new MR-TADF emitter designs to circumvent the aforementioned drawbacks. In the first approach, we have designed linearly π-extended boron (B)/Nitrogen (N)-based polyaromatic hydrocarbon (PAHs) for shifting the emission into deep-red region. In the second approach, we have proposed a simple, yet versatile design for constructing narrowband NIR emitters. The rationality of the proposed designs were validated by the preliminary computational studies. This is a highly interdisciplinary project that covers the fields of organic synthesis, computational modelling, physical and optoelectronic characterization, OLED fabrication and testing. This proposal exploits the two-way transfer of knowledge between the host and the applicant, and the state-of-the-art facilities of the host organization.

The objective of the IN4ACT project is to implement structural changes at the Kauno Technologijos Universitetas (KTU) School of Economics and Business through the opening of an ERA Chair in “Industry 4.0 Management and Economics” research, to increase research excellence, socio-economic impact, international reputation, and attractiveness to international talented researchers and students. An ERA Chair holder and a team will be recruited to 1/ Implement an ambitious research agenda on the impact of future manufacturing (Industry 4.0) on management practices and economics; 2/ Drive changes at the KTU School of Economics and Business related with research management and human resources, especially to comply with the ERA priorities; 3/ Improve the School's exploitation, dissemination, and communication capacities; 4/ Grow networks and increase links with stakeholders, especially to increase participation in Horizon 2020.

We propose a radical new solution to the problem of increasing the efficiency of organic light-emitting diodes (OLEDs) based on modifying the light-matter coupling by nanostructures. All previous attempts to increase the efficiency of OLEDs to be competitive with commercial inorganic LEDs have failed. If successful, our new vision for strongly coupled organic light-emitting diodes (SCOLEDs) will bypass the existing technological bottleneck. OLEDs can be fabricated from earth-abundant non-toxic materials using energy-efficient processes, in stark contrast to the present market-leading inorganic LEDs. However, despite their much lower environmental impact, the widespread deployment of OLEDs has been blocked by their limited efficiency. To achieve the required step-change in efficiency, plasmonic nano-particle arrays will be used to enhance the coupling between light and matter within OLEDs. Our objectives are to enhance OLED efficiency to a level competitive with inorganic LEDs, and at the same time to adjust the periodicity, size and shape of the nanoparticles to control the color, polarization and directional distribution of the emitted light. Analytic theory, numerical simulations and nanofabrication will be combined with optical and electronic characterization across an interdisciplinary team with expertise ranging from materials science and electronics to photonics and quantum physics, including world-leading proficiency in nanoparticle arrays and strong light-matter coupling. Our ambitious target is the proof-of-principle demonstration of an OLED with more than 50% external quantum efficiency and tailorable control of the properties of the emitted light. SCOLEDs offer the prospect of a breakthrough technology that will dramatically reduce the environmental impact of LED technology in lighting and display applications, and will widen the palette of OLED applications to new and emerging areas such as electronic vehicles, augmented reality and urban agriculture.
