Key Points

  • The research aims to understand the microscopic mechanism behind the persistent luminescence in Cr3+-doped ZnGa2O4 phosphors.
  • Analyzed the charge distribution in Cr3+-doped ZnGa2O4 phosphors
  • Investigated the effects of external field stimulation on luminescence
  • Utilized spectroscopic techniques to assess luminescence properties
  • Identified dynamic distribution of charges as a key factor in persistent luminescence
  • Demonstrated the influence of external fields on the afterglow properties
  • Found that Cr3+ ions significantly enhance red afterglow capabilities

Abstract

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...
