摘要
Organic light-emitting diodes (OLEDs) meet the increasingly demanding requirements for active-matrix displays and lighting due to their unique advantages, such as self-illumination, fast response time, low power consumption, and high flexibility. Therefore, OLED-related technologies attract both interests from fundamental research and industry. OLEDs are an excellent convergence of the interdisciplinary research of material science, semiconductor devices, and thin film technologies. This chapter compiles and overviews the key functional materials used in OLEDs, especially for the emitters, and their luminescent mechanisms. Particularly, the solution-processable materials and devices are compared. Unlike the complicated and expensive vacuum evaporation technology, solution processing is more feasible for large-scale production of OLEDs based on either small molecules or polymers, which could be converted into a thin film by means of the technologies such as spin coating, inkjet printing, roll-to-roll printing, and blade-coating.
