Surface Plasmon Coupling: Fundamentals and Applications to Light-Emitting Devices provides readers with a systematic understanding of the principles of surface plasmon coupling, along with its key applications. It addresses essential concepts of surface plasmon coupling – including coupling mechanisms and their application in light-emitting devices – and it offers practical insights through methodologies, experimental techniques, and case studies. Surface plasmon coupling is a useful technique for enhancing the emission efficiency of a light emitter and the color conversion efficiency for display applications. However, there are many common misconceptions around this topic, for example, even the fundamental differences between surface plasmon resonance and surface plasmon coupling are often misunderstood. These misconceptions are compounded by a general lack of systematic explanation of surface plasmon coupling's basic principles when discussing its applications. For this reason, this book first provides a clear explanation of surface plasmon coupling fundamentals before providing practical examples. This approach will help readers understand how an application can be implemented, and also allow them to truly grasp how broad the application scope is. The book offers a fully comprehensive approach, encompassing foundational theories, advanced developments, case studies, and discussions. - Offers a systematic explanation of the basic principles and fundamental characteristics of surface plasmon coupling - Provides practical examples of surface plasmon coupling applications such as light-emitting diodes and color-conversion devices - Discusses related near-field electromagnetic interactions for practical applications - Includes review questions and answers
