LEDs form the backbone of our modern, digitalized and globalized society, ranging from lighting all the way to optical communication, as well as in the displays that surround us in smartphones and monitors in everyday life. Therefore, photonic sources also form a significant and ever-growing fraction of the world’s energy consumption, meaning advances in making LEDs more energy-efficient are crucial for a sustainable energy future. We work on the next generation of solution-processable light-emitting materials based on semiconductor nanocrystals and molecules which enable the production of flexible displays. Using short laser pulses we explore the ways these materials interact with – and emit – light, in order to inform the chemical design of making them even better in doing so in the future. We also tailor these materials towards novel optoelectronic properties by bestowing the light with a defined polarization, enabling even more energy-efficient displays that make your smartphones batteries last longer, and unlocking entirely new applications in the area of quantum information science.
