Since its first discovery by Destriau in oil dispersion of ZnS:Cu phosphors, alternating current electroluminescence (ACEL) has found enormous applications in lighting, full-color displays, and optoelectronics. ACEL materials are particularly useful for constructing flexible light-emitting devices owing to their low cost and easy integration with flexible electrodes and polymer substrates. ACEL devices utilizing the phosphor-elastomer composite as the emissive layer are intrinsically stretchable/deformable, in contrast to direct current light-emitting diodes that are often built on rigid panels. In this Research Update, we summarize recent advances in the design and preparation of various flexible-panel ACEL devices. Emerging applications enabled by these flexible ACEL devices are also highlighted.

柔性交流电致发光器件的最新进展

自从Destriau在ZnS：Cu磷光体的油分散体中首次发现以来，交流电致发光（ACEL）在照明，全色显示器和光电领域已得到了巨大的应用。由于其成本低并且易于与柔性电极和聚合物基板集成，因此ACEL材料特别适用于构造柔性发光器件。与通常建在刚性板上的直流电发光二极管相反，利用磷光体-弹性体复合材料作为发光层的ACEL器件本质上是可拉伸/可变形的。在本研究更新中，我们总结了各种柔性面板ACEL器件的设计和制备方面的最新进展。这些灵活的ACEL设备支持的新兴应用程序也将突出显示。
