First-principles ΔSCF and Huang-Rhys calculations validate the Eu-N₉ coordination model in β-SiAlON:Eu²⁺ at low z and explain the red-shift of emission via zero-phonon line trends, modest Huang-Rhys increases, and configurational diversity.
New non-adiabatic expressions for the partial-FM-occ term yield the most accurate ab initio total energies for carbon polymorphs by incorporating complete EPI physics.
