Near-infrared persistent phosphors (NIR-PPs) are an emerging category of luminescent materials that can continuously emit NIR luminescence with super-long decay time of minutes, hours, or even days after the excitation ceases. Their unique excitation-free long-lasting afterglow, together with the NIR emission, has not only attracted wide research interests in the areas of photochemistry, photophysics, spectroscopy, and materials science, but also stimulated advanced applications in biosensing, bioimaging, biomedicine, and therapy in the past decade. Beyond these bio-related applications, the active research field triggers a number of novel applications recently. In this review, a brief outline of NIR-PPs including the luminescence mechanism, main material systems, and how they were applied into various fields was depicted. Particular emphasis was put on the emerging applications outside the field of biology. Future perspectives in this exploration research area were also presented. We hope this review can help researchers grab the latest information in the fast-growing field of NIR-PPs.
近红外持久磷光体（NIR-PPs）是一类新兴的发光材料，在激发停止后，它们能够持续发射近红外光，具有长达数分钟、数小时甚至数天的超长衰减时间。它们独特的无需激发的长效余辉以及近红外发射，不仅在光化学、光物理、光谱学和材料科学领域引起了广泛的研究兴趣，而且在过去十年中还推动了生物传感、生物成像、生物医学和治疗等领域的先进应用。除了这些与生物相关的应用外，这个活跃的研究领域最近还引发了许多新的应用。在这篇综述中，描绘了近红外持久磷光体的简要概述，包括发光机制、主要材料体系以及它们如何应用于各个领域。特别强调了生物学领域之外的新兴应用。还介绍了这个探索性研究领域的未来展望。我们希望这篇综述能够帮助研究人员获取近红外持久磷光体快速发展领域的最新信息。
