As part of LASER Talks Brussels. Hosted by KIKK FESTIVAL.
In an innovative project titled “Lemniscate Cascade,” artists and scientists join forces to unravel the secrets of light-sensitive liquid crystals. This enigmatic material is more than just the stuff of digital displays, but holds the key to the fundamental dialogue between light and soft matter that sparked life on Earth. The artists behind “Lemniscate Cascade” employ laser beams to traverse light-sensitive liquid crystals, setting off a mesmerizing chain of transformations along the beam’s path.
It’s fascinating how the very materials featured in ‘Lemniscate Cascade’ could draw parallels to elucidate the materials and intricate physical processes at the core of this scientific research. The dual-phase nature of liquid crystals and their intriguing response to light might find intriguing correlations with the dual-state duality of singlets and triplets in the realm of OLEDs.
Yoann Olivier researches the future of Organic Light-Emitting Diodes (OLEDs). OLEDs are at the forefront of lighting and display technologies, but there's always room for improvement. This project delves into the world of TADF (Thermally Activated Delayed Fluorescence) to boost OLEDs' efficiency to an astounding 100%. It's a quest to understand the intricacies of singlet and triplet states, influenced by magnetic field effects (MFEs) such as spin-orbit coupling, hyperfine interaction, and the delta g mechanism. Olivier's multi-scale approach tackles these challenges, offering new perspectives for material design.
