Electrochemiluminescence (ECL) has continued to receive considerable attention in various applications, owing to its intrinsic advantages such as near-zero background response, wide dynamic range, high sensitivity, simple instrumentation, and low cost. The ECL luminophore is one of the most significant components during the light generation processes. Despite significant progress that has been made in the synthesis of new luminophores and their roles in resolving various challenges, there are few comprehensive summaries on ECL luminophores. In this review, we discuss some of the recent advances in organic, metal complexes, nanomaterials, metal oxides, and near-infrared ECL luminophores. We also emphasize their roles in tackling various challenges with illustrative examples that have been reported in the last few years. Finally, perspective and some unresolved challenges in ECL that can potentially be addressed by introducing new luminophores have also been discussed. Graphical abstract.
电化学发光（ECL）由于其固有优势，例如近零背景响应、宽动态范围、高灵敏度、仪器简单和低成本，在各种应用中继续受到广泛关注。在发光过程中，ECL 发光体是最重要的组件之一。尽管在合成新型发光体及其在解决各种挑战中的作用方面已经取得了重大进展，但几乎没有关于 ECL 发光体的全面总结。在这篇综述中，我们讨论了一些最近在有机、金属配合物、纳米材料、金属氧化物和近红外 ECL 发光体方面的进展。我们还强调了它们在解决过去几年中报道的各种挑战中的作用，并通过实例进行了说明。最后，还讨论了 ECL 中可能通过引入新型发光体来解决的一些观点和未解决的挑战。
