Ultraviolet irradiation-responsive dynamic ultralong organic phosphorescence in polymeric systems

Nature Communications, 2021
Efficient stimulus-responsive phosphorescence organic materials are attractive, but are extremely rare because of unclear design principles and intrinsically spin-forbidden intersystem crossing.

Persistent luminescence in Eu2+-doped compounds : a review [PDF]

, 2010
In 1996, Matsuzawa et al. reported on the extremely long-lasting afterglow of SrAl2O4:Eu2+ codoped with Dy3+ ions, which was more than 10-times brighter than the previously widely used ZnS:Cu,Co.
