Preparation and Application of Inorganic Persistent Luminescent Composite Materials

Persistent luminescent materials are photoluminescent materials that store energy when exposed to light and slowly release it as light when the light source is removed. Among them, the inorganic persistent luminescent materials because of its unique characteristics of long afterglow luminescence that make them useful in various fields, including data storage, information technology, photocatalysis, and biomedicine. Researchers have developed multifunctional composites based on inorganic persistent luminescent materials to enhance their properties and functions. However, there is still a lack of a systematic and comprehensive review of inorganic persistent luminescent composite materials. This paper summarizes the preparation methods of inorganic persistent luminescent composites, combining recent literature reports on inorganic persistent luminescent composites and the research work of our group, and then focuses on the progress of the research and application of inorganic persistent luminescent composites in photocatalysis, biomedicine and anti-counterfeiting. Finally, the opportunities and challenges for the practical application of inorganic persistent luminescent composites are analyzed from a prospective point of view.
