Abstract

Organic light-emitting diode (OLED) technology has made significant advances in performance and becoming widely used in smartphone displays. However, the stability of efficient blue emitters, such as phosphorescent and thermally activated delayed fluorescent emitters, remains a challenge. While white OLEDs have the potential to revolutionize indoor lighting, their high cost per lumen due to efficiency roll-off and manufacturing costs is a limiting factor. To overcome these challenges, researchers must explore new material systems and device architectures to reduce efficiency roll-off and develop cost-effective film preparation processes. With continued increases in stability and decreases in cost, there is significant interest in scaling up OLED lighting and exploring its applications in other fields such as biomedical devices, anti-counterfeit labels, and optical communication. © 2023 The Authors

Funding

Chun-Sing Lee is a Chair Professor of Materials Chemistry and the Dean of the College of Science at City University of Hong Kong. He obtained his BSc and Ph.D. degrees from the University of Hong Kong in 1987 and 1991, respectively. After completing his Ph.D., he embarked on his research career at the University of Birmingham in the UK with the support of the Croucher Foundation Fellowship. He joined City University of Hong Kong in 1994 and co-founded the Center of Super-Diamond and Advanced Films (COSDAF) in 1998, where he served as the Center\u2019s Director/Deputy Director until 2022. His research interests include organic electronic devices and nanomaterials for energy, environmental, and biomedical applications.
