In recent years, the research and development of perovskite long afterglow materials has received extensive attention. In this paper, we review the research progress of ABO 3 -type inorganic halide perovskite (including semiconductor and metal halides) long afterglow materials. Initially, we have introduced in detail the afterglow properties of perovskite long afterglow materials (including the afterglow wavelength, afterglow intensity, and afterglow time), their afterglow mechanism (based on the three most widely accepted basic theoretical models, namely the conduction band-valence band model, quantum tunneling model, oxygen vacancy model, and the complex experimental models of specific materials) and afterglow applications (including optical information storage, information encryption, anti-counterfeiting, X-ray detection and imaging, and biological imaging and therapy). Finally, the customization and regulation of the afterglow properties of perovskite long afterglow materials, the expansion of their applications, and the development of perovskite matrix materials are prospected, hoping to provide a reference for the reasonable design and application of long afterglow materials in the future. The mechanism and properties of perovskite long afterglow materials and their applications in biological imaging, information storage, anti-counterfeiting, and other fields.
