Summary: Persistent luminescence (PL) is a unique optical phenomenon that exhibits long-lasting afterglow emissions, making it highly promising for various applications. However, there is a lack of comprehensive literature review on inorganic persistent phosphors to aid researchers in optimizing the PL performance. In this work, the authors provide a review on the criteria for dopant and host selection, afterglow intensity, and multi-color modulation methods of inorganic persistent phosphors. They also discuss PL imaging and multimodal imaging using X-ray, light emitting diode (LED), ultraviolet (UV), and near-infrared (NIR) excitation. This review serves as a guideline for the design, synthesis, and optimization of optical performance of persistent materials in the future.
