Implication

Theoretical analysis reveals nonrandom defect distribution governed by ionization potentials in inorganic phosphors, indicating design principles for improved luminescent materials.

Key Points

Investigate phosphorescence mechanisms in inorganic phosphors by modeling the interactions between dopant cations, co-dopant cations, and crystal vacancies.
Modeled interactions between dopant cations, co-dopants, and lattice vacancies across multiple inorganic solid phosphors.
Used the ionization potentials of host cations, dopants, and co-dopants to assess defect clustering tendencies.
Dopant and co-dopant cations assemble in a nonrandom spatial distribution around lattice vacancies rather than dispersing uniformly.
Relative ionization potentials of constituent cations predict clustering behaviors that strongly govern phosphorescent and fluorescent properties.
