Abstract

An approach to increase the efficiency of europium-based OLEDs was proposed through the formation of a mixed-ligand complex. The design of a series of europium complexes, together with an optimization of the solution deposition, including the host selection, as well as the variation of the solvent and deposition parameters, resulted in a noticeable increase in OLED luminance. As a result, the maximum luminance of the Eu-based OLED reached up to 700 cd/m, which is one of the highest values for an Eu-based solution-processed OLED. Finally, its stability was investigated.

摘要

通过形成混合配体络合物，提出了一种提高铕基有机发光二极管（OLED）效率的方法。一系列铕络合物的设计，以及溶液沉积的优化，包括主体选择、溶剂变化和沉积参数，导致OLED亮度显著增加。结果，基于铕的OLED的最大亮度达到700 cd/m²，这是基于铕的溶液处理OLED的最高值之一。最后，对其稳定性进行了研究。
