First-principles Study of the Luminescence of Eu2+-doped Phosphors

Yongchao Jia, Anna Miglio, Samuel Poncé +2

The luminescence of fifteen representative Eu $^{2 +}$ -doped phosphors used for white-LED and scintillation applications is studied through a Constrained Density Functional Theory. T…

First-principles study of Ce $^{3 +}$ doped lanthanum silicate nitride phosphors: Neutral excitation, Stokes shift, and luminescent center identification

Yongchao Jia, Anna Miglio, Samuel Poncé +2

We study from first principles two lanthanum silicate nitride compounds, LaSi $_{3}$ N $_{5}$ and La $_{3}$ Si $_{6}$ N $_{11}$ , pristine as well as doped with Ce $^{3 +}$ ion, in view of ex…

Precise effective masses from density functional perturbation theory

Jonathan Laflamme Janssen, Yannick Gillet, Samuel Poncé +3

The knowledge of effective masses is a key ingredient to analyze numerous properties of semiconductors, like carrier mobilities, (magneto-)transport properties, or band extrema cha…
