First-Principles Study of Antisite Defect Configurations in ZnGa2O4:Cr Persistent Phosphors.


Zinc gallate doped with chromium is a recently developed near-infrared emitting persistent phosphor, which is now extensively studied for in vivo bioimaging and security applications. The precise mechanism of this persistent luminescence relies on defects, in particular, on antisite defects and antisite pairs. A theoretical model combining the solid host… (More)
