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.
