Project description
Chiral light solution increasing imaging and display efficiency
Chiral light, a discovery dating back centuries, is a form of light that delivers either left or right optical information depending on its polarisation. It has the potential to offer various benefits in optoelectronics, quantum optics, and spintronics. However, despite its early discovery, traditional methods for switching its emission have been inefficient and slow, making them suboptimal. In this context, the ERC-funded FastE-Chiral project will create specific chiral environments for emitters that significantly enhance speeds and efficiency. The results of this research are expected to provide greater control over chiral light and facilitate easier generation, offering crucial benefits for the future of imaging and display technology.
Objective
Chiral light, with a rotating electromagnetic field, is revolutionizing optoelectronics, quantum optics, and spintronics. This unique light delivers either 'left' or 'right' optical information based on its polarization, similar to how alternating electrical signals transfer sound and images. Despite centuries since the discovery of chiral light, achieving electrical modulation of its handedness in light-emitting devices remains a significant challenge.
Traditional methods of switching chiral emission handedness, e.g. inverting material stereochemistry or mechanically rotating optical filters, encounter practical limitations: complicated fabrication and slow switching speeds. However, electrical modulation of light handedness simplifies manufacturing processes, and enable in-situ controllability. This allows for not only the switching of handedness but also capability to do so at high frequencies.
My approach departs from prior research. Instead of focusing on emitters, I will investigate the largely overlooked molecular environment of these emitters—the host materials. These materials account for ~90% of host-emitter blends and significantly influence the transport properties of organic light-emitting devices, but their role has been surprisingly neglected in previous research.
My objective is to create a chiral environment for emitters using chiral host materials, thereby manipulating electron behavior. Such transport behavior will ‘polarize’ the entire recombination processes, making the chiral emission handedness dependent on current flows. Integrating these materials into a new chiral organic light-emitting transistor, the goal is to achieve ultra-fast handedness switching of highly polarized chiral emission within a single device.
Despite notable challenges, creating such light sources offers direct chiral light generation and rapid control over its handedness, potentially revolutionizing future optical communication, imaging, and display technologies.
