“…For instance, even if the strontium aluminates have been known for about three decades and have been largely investigated, some doubts still remain about the role of the native defects and dopants in the trap generation and the trapping–detrapping processes . However, in some cases, the hole and trap centers were identified, e.g ., Pr 3+ and Tb 3+ in lanthanide-based oxysulfides and the oxygen and germanium vacancies in (Sr/Ba) 1– x Ca x Ge 4– y O 9 :Mn 2+ …”

Persistent luminescence materials are compounds able to glow in the dark after proper excitation. After the discovery in the 1990s of the long persistent luminescence in SrAl 2 O 4 :Eu 2+ ,Dy 3+ lasting 12 hours, the interest in this class of materials has grown quickly. Today, thousands of compounds are known to possess persistent luminescence, and some of them have found real industrial applicability. However, the mechanism driving the persistent luminescence remains somewhat unknown. The scenario is further complicated by moving from bulk materials to nanocrystals. Herein, we give an overview of the most important goals achieved in persistent luminescence materials and a critical perspective on this peculiar phenomenon at the nanoscale.
