Insights into the microscopic mechanism of persistent luminescence in Cr3+-doped ZnGa2O4 phosphors, suggesting new pathways for material design.
Persistent luminescence (PersL) phenomenon is the result of dynamic distribution of microscopic charges caused by an external field stimulation. A long-standing unresolved question is that why red afterglow phosphors activated...
