本文介绍了评价离子液体（ILs）作为潜在的电解质的单层发光器件具有良好的发射性能。随着光电子器件的不断丰富，具有单个发射层的高性能发光器件对于低成本生产变得越来越重要。我们表明，一个简单的技术，将IL的聚合物层可以导致高的发光效率和良好的响应时间的单层发光聚合物，即使没有额外的堆叠的电荷载流子注入和传输层。从能量图和电极上双电层的角度讨论了IL对聚合物发光的贡献。我们的发现使发光器件的生产更快，更便宜，更低的浪费。
This paper describes an evaluation of ionic liquids (ILs) as potential electrolytes for single-layered light-emitting devices with good emission performance. As optoelectronic devices continue to grow in abundance, high-performance light-emitting devices with a single emission layer are becoming increasingly important for low-cost production. We show that a simple technique of osmosing IL into the polymer layer can result in high luminous efficiency and good response times of single-layered light-emitting polymers, even without the additional stacking of charge carrier injection and transport layers. The IL contributions to the light-emission of the polymer are discussed from the perspectives of energy diagrams and of the electric double layers on the electrodes. Our findings enable a faster, cheaper, and lower-in-waste production of light-emitting devices.
