Highly efficient tunable white emission with ultralong afterglow in Sb 3+ /Mn 2+ -codoped CsCdCl 3 crystals for multifunctional applications

, which enables the rapid release of trapped carriers to the emission center and rejuvenates afterglow emission after 12 h pre-delay. Finally, we demonstrated the applications of the as-synthesized compounds in single-component white light illumination, multiple optical anti-counterfeiting and information encryption.
