The past several years have witnessed the tremendous development of novel chemical structures, new design strategies and intriguing applications in the field of room-temperature phosphorescence (RTP) and organic afterglow materials. This Review article focuses on recent advancements of high-performance organic afterglow materials obtained by two-component design strategies such as a dopant-matrix, donor-acceptor, sensitization, and energy-transfer strategies. Based on some cutting-edge studies, organic afterglow efficiency has been largely improved, exceeding 90 % in several cases. Organic afterglow durations reach tens of seconds in phosphorescence systems and hours in donor-acceptor systems. Organic afterglow brightness outcompetes some inorganic afterglow materials in the first several seconds after ceasing excitation source. Organic afterglow colors cover the whole visible regions and extend to near-infrared regions with respectful afterglow efficiency. On the basis of these achievements, researchers demonstrate promising applications of organic afterglow materials in diverse fields, which has also been reviewed.
在过去的几年里，室温磷光（RTP）和有机余辉材料领域见证了新型化学结构、新设计策略以及引人入胜的应用的巨大发展。这篇综述文章聚焦于通过诸如掺杂剂-基质、供体-受体、敏化和能量转移策略等双组分设计策略获得的高性能有机余辉材料的最新进展。基于一些前沿研究，有机余辉效率有了很大提高，在某些情况下超过了90%。在磷光体系中，有机余辉持续时间可达数十秒，在供体-受体体系中可达数小时。在停止激发源后的最初几秒内，有机余辉亮度超过了一些无机余辉材料。有机余辉颜色覆盖了整个可见光区域，并以可观的余辉效率延伸至近红外区域。基于这些成果，研究人员展示了有机余辉材料在不同领域的广阔应用前景，本文对此也进行了综述。
