Full-color persistent luminescence tuning: A marriage of perovskite quantum dots and lanthanide ions

In modern society,the developments of luminescent materials capable of emitting various colored lights are critically important for lighting and display systems[1–3].As a typical kind of luminescent materials,the persistent luminescence phosphors have been widely investigated as night-light vision materials due to their many significant applications such as emergency route signage and security signals,biolabels,photocatalysts,anti-counterfeiting,optical sensors,and optical data storage[4–6].
