Advancing Organic Materials: Research Breakthroughs from HELIOS at Kaunas University of Technology
In a significant milestone for the HELIOS project, Stepan Kutsiy, an experienced researcher from the Department of Electronic Engineering (ELI) at Lviv Polytechnic National University, recently completed a research visit to Kaunas University of Technology (KTU). This collaboration is crucial in advancing the development of innovative organic materials for next-generation white organic light-emitting devices (WOLEDs).
Key Research Findings
High Thermal Stability: The organic materials LK-161 and LK-162, provided by our partners from Glasgow, demonstrated remarkable thermal stability. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) confirmed only a 5% mass loss at 395°C (LK-161) and 389°C (LK-162), showcasing their potential for stable, long-lasting applications.
Photoluminescence Properties: Comprehensive studies were conducted to examine:
Spectral characteristics in various solvents,
External quantum efficiency,
Absorption spectra,
Lifetime properties in thin-film form. These findings will be instrumental in optimizing material performance for efficient lighting applications.
Electrochemical Properties & Charge Transport:
The electrochemical properties of the materials were assessed using photoelectron emission spectroscopy.
Hole mobility was measured via the Time-of-Flight (TOF) method, analyzing pre-deposited layers.
Advanced Research Methods
The study employed a state-of-the-art FLS980 Edinburgh Instruments spectrometer, ensuring precise optical and electronic measurements. This high-precision data will directly contribute to optimizing WOLED fabrication at Lviv Polytechnic.
The Impact of the HELIOS Project
The HELIOS project unites leading European universities and research institutes to pursue cutting-edge organic material innovation. By combining international expertise and resources, HELIOS is pushing the boundaries of sustainable lighting solutions.
Looking Ahead: The next phase of this research will involve integrating these novel materials into prototype WOLED devices, which will be developed and tested at Lviv Polytechnic’s Electronic Engineering Department. This collaboration underscores the vital role of international partnerships in accelerating scientific breakthroughs.
A special thanks to all partners and researchers who contributed to this remarkable achievement. Stay tuned for further updates on the progress of the HELIOS project!
