| Abstract Scope |
Remarkable progress has occurred in the development of persistent luminescent (PersL) materials owing to their unique “self-luminescing” feature and broad potential applications. Pr3+ is one PersL emitter which could cover the full spectral range from ultraviolet to infrared due to its manipulable 4f5d → 4f2 inter-configurational and 4f2 → 4f2 intra-configurational transitions in appropriately designed hosts. Here, we reviewed the advancements in Pr3+-activated PersL phosphors to provide some guidelines for design new PersL phosphors. The advancement and plausible mechanisms of Pr3+-activated visible and infrared PersL phosphors were discussed as “self-luminescing” probes in night-vision surveillance and bio-imaging. The more recently reported UV PersL phosphors activated by Pr3+ have boosted new exciting applications such as “solar-blind” imaging. The perspectives for Pr3+-activated persistent phosphors are addressed. This review is expected to further motivate development of high-performance persistent phosphors regarding their potential applications along with understanding their composition–structure–property relationship. |
