Solution-Processed Organic Light-Emitting Devices

Solution-Processed Organic Light-Emitting Devices provides a comprehensive reference on the principles and advances in materials design, device structures, and processing technologies of organic light-emitting diodes (OLEDs). Most importantly, the book analyses the dynamics of thin-film growth from solutions such as solvent orthogonalization, coffee-ring effects, and interfacial adhesion. Exciton generation and utilization, host–guest energy transfer, and interfacial interaction in the solution-processed films are considered with the material and device design to maximize the electroluminescent performance of OLEDs.The book reviews the materials, devices, and technologies dedicated to solution-processed thin-film devices, which are not only applicable to OLEDs but may be adapted to other emerging semiconducting devices due to the similarity in methods (for instance, quantum-dot LEDs and solar cells, and perovskite-based LEDs/photovoltaics/detectors).This book is suitable for researchers in academia and industry working in the materials science and engineering, chemistry, and physics disciplines.

• Discusses the most relevant and emerging solution-processable materials for OLED applications
• Reviews device engineering to address defects, charge transport, and exciton generation in fabricated solution-processable thin films
• Provides the methods to grow multilayered thin films from solutions with organic semiconductors, with particular attention to new technologies to overcome interfacial mixing effects

Guohua Xie is a full professor at the Institute of Flexible Electronics (Future Technologies) of Xiamen University, focusing on the interdisciplinary research of solution-processed organic optoelectronic materials and devices. He worked on OLED microdisplays and obtained his PhD degree from Jilin University (China) in 2011. He carried out his postdoctoral research investigating the stability of OLEDs at TU Dresden (Germany), sponsored by the Alexander von Humboldt Foundation. Dr. Xie worked for an OLED-based interdisciplinary project funded by the Engineering and Physical Sciences Research Council (EPSRC, United Kingdom) at the Organic Semiconductor Center of the University of St Andrews from January 2013 to January 2015 and was admitted as a Fellow of the Royal Society of Chemistry in 2020. Dr. Xie served as an associate professor at the College of Chemistry and Molecular Sciences of Wuhan University (China) between 2015 and 2022. He has coauthored more than 200 peer-reviewed publications and contributed to three edited book chapters on organic optoelectronics.
