in a microscopic view
Not only is this relevant from a fundamental perspective. It also opens up a strategy to make use of either intrinsically present or dopant-induced trapped charge carriers and defects as redox partners in solids for the synthesis of potential phosphors on the basis of reduced activators, such as the divalent lanthanides, without the necessity of employing challenging reducing conditions in the preparation.
